With his players seemingly dropping like flies, Jose Mourinho could do with every man he can lay his hands on, so the manager will have been relieved yesterday to hear Michael Ballack commit his future to Chelsea. The Germany midfield player has attracted strong interest from Real Madrid, with Spanish sources making the outlandish claim over the weekend that he had agreed to accept a pay cut to move to the Bernabeu, although Ballack insists that he wants to stay.

Ballack is recovering from the ankle operation that brought a premature end to a disappointing first season at Chelsea, but he is determined to prove himself to his

critics. The 30-year-old sought reassurances from Mourinho and Peter Kenyon, the chief executive, that he was wanted by the Chelsea hierarchy over the weekend and with his confidence restored yesterday, decided to go public.

“I am totally committed to Chelsea,” Ballack said. “I came here to win trophies, to be successful in English football and I want to assure the Chelsea fans of that. I am very happy in London professionally, and for my family. The speculation about me leaving is not true. I have had no contact with Real Madrid whatsoever. I am frustrated by my injury, but I am working hard to be fit and hope to be back very soon to join my teammates.”

Ballack's words will come as a serious blow to Real, who identified him as their main summer transfer target after missing out on Kaka, the

AC Milan and Brazil midfield player, and even claimed that a five-year deal was in place. The Spanish club's attempt to unsettle Ballack has served only to antagonise Chelsea, with whom they are still negotiating over the transfer of Arjen Robben. The Holland winger's move is likely to go through before the end of the month, but Chelsea are determined to hold out for a fee of £25 million.

Ballack will be of little use to Mourinho in the short term, with his ankle problem showing few signs of improvement. The Portuguese has 13 first-team players receiving treatment for a variety of ailments, although at least five of them should be fit to play in the club's Barclays Premier League opener at home to Birmingham City on Sunday.
