Chelsea defender David Luiz has said that his two years away with Paris Saint-Germain helped him to return to the club as a better player.
The 29-year-old spent three years with the Blues, winning the Champions League, Europa League and the FA Cup before moving to the Ligue 1 side in a £50m deal in 2014.
After just two seasons in France, Luiz returned to Stamford Bridge in August, having claimed two league titles and four pieces of silverware during his brief stint.
Asked if he is now performing at a higher level for Chelsea than during his first spell, Luiz told the Evening Standard: "Yes, if not that means I'm going the wrong way. You need to be ready to improve every day and be available to do that immediately, from your first day. If I think I am the same player as many years before, this is not a good mentality.
"I improve every day. It was a new league with a new philosophy [at PSG], different players and a different culture, so I was happy there. I won a lot and learnt a lot.
"When you get older, you want to organise your bedroom more than when you are young, no? It's quite like this, just part of getting older."
Since his deadline-day return Luiz has featured 10 times for Chelsea, who are currently three points clear at the top of the Premier League.
