Read how all the action unfolded below:
3.32pmGood afternoon! Chelsea get their final European tour match underway in around half an hour. They've named a strong team for the outing, so let's take a look at the lineups...
3.33pmCHELSEA STARTING XI: Courtois, Azpilicueta, Zouma, Terry, Luis, Van Ginkel, Matic, Salah, Fabregas, Torres, Costa
3.35pmCHELSEA SUBSTITUTES: Cech, Ivanovic, Ake, Hazard, Mikel, Drogba, Cahill, Chalobah, Baker, Christensen, Boga, Solanke
3.38pmSo new signings Cesc Fabregas, Filipe Luis and Diego Costa are all in the starting lineup, while the re-signed Didier Drogba starts on the bench. According to the club's Twitter account, Drogba, Petr Cech, Eden Hazard and John Obi Mikel will also feature in the second half.
3.42pmIt is interesting to note that Courtois gets the nod to start ahead of Cech in goal today. The keepers are battling for to be Jose Mourinho's first choice between the posts. On the subject of the competition between the duo, Mourinho said: "It was logical that Courtois had to be back. It would be nonsense to have such a fantastic young goalkeeper and not to have him back. That decision was an easy one. If I have to make a decision for Cech to be on the bench, or for Courtois to be on the bench, it's no problem for me. I will do what I think is the best."
3.46pmMourinho has been patrolling the side of the pitch signing autographs for fans, although this young Bremen fan doesn't look too happy about the Chelsea manager signing his shirt:
Werder Bremen (@werderbremen) August 3, 2014
3.50pmWe don't have the full Bremen team news yet, but we do know that former Chelsea man Franco di Santo is in their starting lineup. The striker left Chelsea in 2010 to join Wigan before moving to the Bundesliga in 2013.
3.54pmPREDICTION! With just a few minutes until kickoff, let's make a prediction! Pre-season games are always a bit tricky to call while players are still getting used to being back in training, but Bremen have certainly looked good in their matches so far this summer, although Chelsea do have a strong side. I can see this one being a draw, so I'm going for 2-2.
3.57pmBREMEN STARTING XI: Wolf, Fritz, Lukimya, Caldirola, Garcia, Galvez, Bartels, Obraniak, Junuzovic, Di Santo, Elia
3.39pmThe teams are just making their way out in front of a packed Wesser Stadium. Kickoff should just be a few moments away.
1 minKICKOFF! Chelsea get the match underway.
2 minChelsea immediately have a free kick as Fritz charges into Torres. The striker is left rubbing his ankle after quite a heavy collision, but he's quickly back on his feet.
5 minChelsea have had the majority of the ball in the opening couple of minutes, but Fritz wins it back for the hosts and tries to get it forward for the German side, but Elia can't control the delivery, and it goes out for a throw in. There have been no chances of note as yet, but it's still early days.
8 minMatic makes a break for the visitors, shrugging off a couple of challenges before crossing into the box for Torres, but the Spaniard is being too closely marked and can't get his shot way, allowing Bremen to make the clearance.
10 minMore positive play from the visitors as Diego Costa puts the Bremen defenders under pressure, collecting the ball from a back pass, but Wolf did enough to clear the danger.
11 minCHANCE! Thibaut Courtois has made his first ever save in a Chelsea shirt! The Belgium international is tested when Di Santo tries to head in from close range, but Courtois reads it well and punches it away.
13 minBremen are starting to look a little more threatening, with Fritz making a run from inside his own half to have a shot, but Terry was there to make the block.
16 minCHANCE! Costa seems to be a marked man as he's fouled twice in the space of two minutes. The second gives Chelsea a free kick just outside the box, which Fabregas curls in towards Zouma, bu the centre-back couldn't quite reach it in time.
20 minGOAL! Bremen 1-0 Chelsea (Elia pen.)
20 minA brilliant ball forward from Fritz left Chelsea wide open and the back, and Terry just appeared the catch the ball with his arm while racing to get back. There was some doubt as to whether the hand ball was in the box or not, but there was no doubt about Eljero Elia's spot kick, as he drilled it in low to the far right of the goal. Courtois went the right way, but just couldn't stretch far enough.
23 minBremen have naturally been boosted by the goal, and are enjoying the majority of the possession at the moment. However, Chelsea have quickly got organised at the back to make sure that the hosts don't get a quick chance to add a second.
26 minDi Santo tries to set Elia up again following another good through ball from Fritz, but the former Chelsea man mis-times his pass, and it goes straight to Azpilicueta.
27 minChelsea's Twitter feed is full of optimism, despite the team going a goal down:
We've already come from behind on three occasions during pre-season, let's hope we can do it again. #CFCLive— Chelsea FC (@chelseafc) August 3, 2014
30 minFabregas has been involved almost every time Chelsea have pushed forward so far, and he's involved again as he curls in towards Costa, but it's a little too high, allowing Wolf to gather before the keeper wins a free kick as Costa, who had already committed to a header, clatters into him.
33 minMatic launches a long ball forward into the box, but Wolf comes off his line to claim it before any of the Chelsea players waiting in the box can reach it. The Bremen goalkeeper really hasn't been tested yet.
36 minChelsea have had the majority of the ball in the last five minutes, but are still yet to create a real goal-scoring opportunity. Azpilicueta manages to find an unmarked Torres with a curling ball into the box, but the Spain international smashes his shot well over.
37 minGOAL! Bremen 2-0 Chelsea (Obraniak)
37 minThe hosts quickly break on the counter-attack and from nowhere they've doubled their lead. Fritz lobs the ball forward, and it drops nicely just inside the box for Ludovic Obraniak, who coolly heads the ball past Courtois. The Polish international isn't known for his heading, but he certainly hit that one well.
40 minBremen are brimming with confidence now, and are pushing to make it three before the break, with Elia and Di Santo teaming up on the edge of the box, but the latter's ball forward for the first goalscorer has too much pace and goes behind for a goal kick.
43 minDISALLOWED GOAL! Mohamed Salah has the ball in the back of the net for Chelsea, having found himself unmarked at close range. Unfortunately for him, he was unmarked because he was offside, something that didn't escape the attention of the assistant referee.
45 minChelsea are on the ball again, but really don't look creating anything in the final moments of this first half.
45 minHALF TIME: Werder Bremen 2-0 Chelsea
4.50pmSo goals from Eljeri Elia and Ludovic Obraniak have given Werder Bremen a 2-0 lead over Chelsea at half time in their pre-season friendly in Germany. It's been a pretty clinical display from the Bundesliga side so far, making the most of their limited chances while defending well against Jose Mourinho's men.
4.53pmChelsea did have the ball in the back of the net, but Bremen goalkeeper Raphael Wolf probably could have got to Mohamed Salah's strike had he not already spotted the offside flag being raised.
4.57pmThe penalty incident was an interesting one. In real time it did appear to strike John Terry's hand, but replays suggest it may he hit his back, as well as being right on the very edge of the box. The Chelsea captain will no doubt feel hard by.
5.01pmIt looks like Chelsea will be making at least one change for the second half, as Petr Cech has got his scrum cap on and has been warming up during the break.
5.04pmThe teams are making their way back out for the second half. We'll bring you all changes as soon as we have them.
46 minBremen get the second half underway.
46 minCech, Ivanovic, Mikel, Cahill and Drogba have all come on for Chelsea at half time.
48 minDrogba, who is playing in a Chelsea shirt for the first time since helping them win the Champions League in 2012, seems keen to make an early impact as he looks to combine with Torres, but Bremen spot the danger.
50 minChelsea win a free kick around 25 yards out, which Fabregas floats in towards Torres, who in turn tries to head on four Drogba, but the Ivorian is offside.
53 minChelsea have certainly looked more attacking at the start of the second half, but are still yet to put the Bremen keeper under pressure. There could be more changes coming though, as Hazard and Ake are warming up.
55 minFabregas is continuing to play a big role in the attack for Chelsea as he tries to pick out Drogba, but puts a little too much on the ball.
56 minPENALTY APPEAL! Chelsea want a penalty as Fritz appeared to catch the ball on his arm while attempting to block a Fabregas cross, but the referee isn't interested.
58 minSUBS! Salah and Torres make their way off as Nathan Ake and Edin Hazard are introduced for the visitors.
61 minAke tries to make an impact, but his first contribution is to give away a free kick. The break in play allows the hosts to make a string of changes.
63 minThere really haven't been any chances in this second half yet, Chelsea have certainly been more attacking than they were in the first half, but still haven't forced a save, while Petr Cech hasn't really had anything to do since replacing Courtois during the break.
67 minCHANCE! Bremen have been enjoying a little more possession in the last couple of minutes, but really haven't looked like adding to their two goals from the first half. Chelsea try to catch them out on the counter-attack, with Hazard slicing the ball through two defender for Fabregas, but the Spaniard finish was a fraction too high.
70 minSUB! Azpilicueta makes way for Jeremie Boga, who immediately looks to set up Drogba, but it comes to nothing.
73 minAke initially came in at the back but has been playing a more advanced role in the last couple minutes as Chelsea try to get back into the match. However, the visitors just don't seem to be gelling up front. There have been so many over-hit balls and miscommunications, but there's is still time for them to salvage something.
76 minSUB! Mourinho makes another change, taking off captain John Terry to bring on young defender Lewis Baker.
79 minAke and Matic play the ball through midfielder before the former regains the ball out wide and tries to cross in for Fabregas, but completely overhits it, and it goes out for a throw in on the opposite side.
82 minA great ball forward from Fabregas leaves Drogba through on goal with only Wolf to beat, but the striker's first touch is poor, and it rolls harmlessly to the Bremen keeper.
84 minChelsea win just their second corner of the game as Matic continues to put the home side's defenders under pressure. However, it's swiftly cleared and Bremen force Cech into action at the other end, but the goalkeeper gets his fingertips to Fritz's shot before Cahill clears.
85 minCHANCE! The second half has suddenly burst into life! Chelsea are straight back in Bremen's box, but Costa rushes his finish, pulling it a fraction wide.
88 minPENALTY TO BREMEN! Ake goes lunging in to give the hosts their second spot kick of the match.
89 minGOAL! Bremen 3-0 Chelsea (Kroos pen.)
89 minFelix Kroos is sent tumbling as Ake brings him down with a tackle from behind, although it did look like he got some of the ball. The referee just books Ake, despite him being the last man, but also gives the hosts the penalty, which Kroos takes himself, and smashes into the left side of the goal.
90 minFULL TIME: Werder Bremen 3-0 Chelsea
5.52pmThere's no time for Chelsea to try and get a goal back as the referee blows for full time. It really wasn't a great display by Chelsea this afternoon, and that's reflected in the scoreline. They did show much more attacking intent after the break, but couldn't get the ball to their strikers.
5.55pmWell that's all from this match, but stick around to read reports from all of the Premier League sides in pre-season action this afternoon. Thanks for joining me this afternoon, goodbye.
