The Czech Republic goalkeeper is out for ten weeks this summer with a dislocated shoulder.
Petr Cech faces a tense summer. The Czech international goalkeeper has been a stalwart at Stamford Bridge in recent years but he has never faced a challenge quite like this since his arrival.
Cech has competition for his spot, serious competition.
Thibaut Courtois joined the club from Genk in 2011 but has never played for The Blues. He has spent his entire time at the club on loan at Atletico Madrid. During his time at the Vicente Calderon the 22-year-old has established himself as the best stopper in Spain and potentially even the best goalkeeper in world football.
Jose Mourinho is now said to want him back in London, after being incredibly impressed by his performance in the Champions League tie between the two clubs.
However it is not just a place in the Chelsea team he has to fight. He is currently battling injury trouble this summer. Cech suffered a dislocated shoulder in the first leg against Los Colchoneros and Courtois recently. He underwent surgery earlier this month, which has ruled him out for 10 weeks.
At least he has a novel way of recovering from the ailment. He has posted a picture on Facebook playing the drums, which could be a very light way of him getting back to full fitness.
Let's just hope he doesn't go too Keith Moon in the rehab - as that can't possibly be good for the shoulders.
