Ballack was injured shortly after missing the games against Manchester United, Liverpool and Arsenal. Ballack's return from injury has been a lift for Chelsea as he set up Deco to score a scissor kick in a 2–0 win against Bolton Wanderers. Ballack's first goal of the '09 season came against Southend United in their FA Cup replay, a match which Chelsea went on to win 4–1.
