Chelsea goalkeeper Asmir Begovic says he is ready to fight to secure a regular place in Jose Mourinho's squad but also that he has received no guarantees from the Portuguese.
The 28-year-old opted to leave Stoke City to move to Stamford Bridge knowing that he would start the season on the bench.
And he says the challenge, boss Jose Mourinho and the top class players in the squad were all reasons why he decided to leave the Potters to join champions Chelsea.
"I want to test myself against Thibaut, he's one of the best goalkeepers in the world but I believe in myself," Begovic is quoted as saying by the Telegraph.
"I want to try and get as many games as I can.
"There have been no guarantees from the manager. The challenge that's here, the manager and players was what attracted to me.
"I'll back myself, absolutely.
"I'll be keeping my head down and working hard to see how I can help this team in the future. Obviously everyone has their opinion but for me it was more of a challenge to try something different.
"I think I was at that stage where I want to test myself against the best and that's ultimately what I've come here to do.
"Hopefully every time I can show everybody what I'm all about and ultimately help this team."
