Werder Bremen loan signing Claudio Pizarro has no regrets over his move to Chelsea last summer.
"A lot has changed and I think Werder have improved in a lot of areas and the team has a lot of quality.
"I want to win things and that is why I am here."
Pizarro concedes that his Chelsea career floundered after Jose Mourinho left as manager to be replaced by Avram Grant.
He added: "It was okay, I mean I still had some positive experiences, but it certainly did not turn out the way I had imagined.
"One of the best coaches in the world wanted to have me in his team, but then three months later he was gone.
"That is just my bad luck, but such is football."
