Michael Ballack says he's loving life working for Chelsea coach Avram Grant.

"At the moment I am completely happy here," said the former Bayern Munich man. "My family and I have adjusted to life in England, I have a contract, and no desire to switch clubs.

"I'm playing for a great team and hope to achieve great things. What comes when my contract expires, we'll just have to see.

"Whether I stay another year, go somewhere else of hang up my boots - you never know in football."
