Cech has been Chelsea's first choice goalkeeper for the last ten years since his 2004 move from French side Rennes, with the Czech Republic international making close to 500 appearances for the Blues on his way to becoming one of the most consistent and dependable goalkeepers in world football.
However, his previously untouchable No. 1 jersey is now in jeopardy after the emergence of Thibaut Courtois. The Belgian international, 22, joined Chelsea from Genk back in 2011, but has been out on loan with Atletico Madrid for the last three seasons, where he has won the La Liga title and reached the Champions League final.
Now considered by many as the second best goalkeeper in the world behind Manuel Neuer, Courtois has dislodged Cech as Chelsea's first choice after Jose Mourinho handed him starts against Burnley and Leicester to begin the Premier League season.
Cech's demotion to the bench has sparked fervent speculation over his future, with the likes of Monaco and Paris Saint-Germain linked with big money moves to take him away from West London and hand him first team football once again - and whilst Chelsea captain John Terry has commended Cech's attitude in training, he also doesn't know how long the 32-year-old can keep fighting for a first team place at Stamford Bridge.
"It is very hard to take for big Petr but he is Chelsea through-and-through has been unbelievable in the way he has responded in training - and in his attitude," he said. "Some players throw their toys out the pram and Petr, 100 per cent has not done that, he is fighting for his place.
"How long he can fight for his place I don't know that. That is a decision for him and the club to decide but we have got two of the best keepers in the world. Petr has done it for many years and if Thibaut can replicate that it will take some doing."
