Bayern Munich midfielder Michael Ballack has agreed to sign a four-year contract with Chelsea, according to reports from Germany.
The German public broadcaster ZDF said all that was left was for Ballack, 29, and Chelsea to sign the contract.
"According to information from ZDF, Michael Ballack and the English champions have agreed a four-year contract," the broadcaster said.
"The captain of Germany and the London club must only sign the contract now."
There has been no official confirmation from either Chelsea or Bayern.
Ballack, who is out of contract at Bayern this summer, is refusing to sign a new deal with the Bundesliga giants and has admitted being in 'serious negotiations' with the Stamford Bridge club.
