Liam Rosenior will manage a Premier League game for the first time on Saturday, when his Chelsea side host Brentford at Stamford Bridge in a West London derby.
The Blues have won one and lost one under the new boss, recently falling 3-2 at the Bridge to cross-town rivals Arsenal in the EFL Cup semi-final first leg defeat after defeating Charlton Athletic 5-1 in the FA Cup third round last Saturday.
With Chelsea not winning a league game in over a month, the London side have slipped to eighth in the Premier League table ahead of this weekend's meeting with the Bees, currently fifth in the top flight.
Here, Sports Mole rounds up the Blues' latest injury and suspension news ahead of their Premier League clash against Brentford, who head into this weekend unbeaten in six league games.
