Thibaut Courtois has admitted he now needs to justify Jose Mourinho's faith in him after taking over from Petr Cech in goal but said it would not have made sense for him to return to Chelsea and sit on the bench.
After three years on loan at Atletico Madrid, the Belgian made his belated Blues debut in their 3-1 win over Burnley on Monday and feels he needs to carry on playing well to keep Cech out of the team,
He said: "It was nice. I came here obviously to play. I know that Petr is a great goalkeeper so there is a lot competition, but when you come back from a successful loan you hope to play. Otherwise, it would maybe have been better for me to go to another team.
"It is nice that he [Mourinho] put faith in me and it is for me now to prove his faith is right. I need to work hard in every training session and game to gain the confidence of my teammates and the manager. Always when you are here you have pressure to perform because you are playing in a top team."
Mourinho has said he does not want to sell Cech, who has been Chelsea's first-choice goalkeeper since his arrival in 2004 and Courtois feels he can benefit from working with the 32-year-old.
He added: "In training I can still learn from him because he has a lot of experience, he can give me good tips about the PL, things I might not know in the start. He is nice to me.
"We are training very well and he is still proving he is a great goalkeeper. For the team is better for us to have two good goalkeepers. I don't have a problem if he stays. Hopefully I can play well and stay in the team."
