Michael Ballack insists Chelsea's Cup eliminations this season have been all their own doing.

Ahead of their Champions League clash with Fenerbahce, the German midfielder said: "We went to the Carling Cup final and we should not have lost it. It was our fault.

"It wasn't that Tottenham played fantastic football. The same against Barnsley. It was our fault, and against Fenerbahce in the first leg it was our fault.

"When we play our best football we can win every competition but we didn't do this in the FA Cup and the Carling Cup and we went out.

"We must use those defeats as our motivation for the second leg against Fenerbahce."
