The suggestion he only moved for the money, however, still rankles, and he insists it was a decision he does not regret.
"There were other clubs that offered me more money to go to them, rather than Chelsea," says Sidwell to the Daily Mail. "They were the champions and when they come knocking on your door and Mourinho says he wants you personally then you don't fancy anything else. A lot of people say I went there for the money, but it wasn't the case.
"I'd rather have finished my career and say I tried to give it a go and it didn't work out, and I can tell my boys and my grandsons that I played for Chelsea, rather than saying: 'Well, I could have played for them.'
"My dad, Gordon, was a Chelsea fan. Not just him - there are quite a lot of Blues fans in my family. If they had found out that I had turned it down there would have been uproar. But I went for footballing reasons only - and that's all that matters."
