Chelsea goalkeeper Asmir Begovic insists that football, not money, was the main reason behind his move to Stamford Bridge.

Begovic joined the champions in a £8million deal from Stoke City to replace Petr Cech who moved to Arsenal.

The Bosnian goalkeeper is now expected to play second fiddle to first-choice Blues goalkeeper Thibaut Courtois but is determined to achieve success with the reigning Premier League champions.

Begovic said: "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.

"Even after the first week you can see the quality here and how they can improve you with the levels and demands here.

"There have been no guarantees. The challenge, the manager Jose Mourinho and players that are all here, was what attracted to me and that was a big part of my decision.

"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."
