Chelsea have confirmed that Germany midfielder Michael Ballack has signed a new one-year contract at Stamford Bridge.
The 32-year-old has been with the Blues for three seasons, scoring 20 goals in 122 appearances in all competitions since his arrival from Bayern Munich.
He told the club's official website: "I am very happy to be staying at Chelsea for one more year as it was always my intention to play in London at least until the World Cup in 2010.
"We had a fantastic end to the season winning the FA Cup and we are all looking forward to taking this success into the new season under Carlo Ancelotti, our new manager."
Ballack had previously said after the FA Cup final victory over Everton at the weekend: "Next year we want to win the Premier League again.
"We know that Manchester United are a very, very good team and they have a good year behind them, so it will not be easy.
"They have won it three years in a row which is a big thing, they can play with confidence and it looks like it is getting easier for them.
"But we have showed this season, especially in the Champions League, that we can play really good football too."
