Chelsea's season will be a failure without silverware, says defender Ricardo Carvalho.

He said: "After we only drew with Wigan on Monday it was obvious that the Everton game was too important a match for us not to play well and show our strength.

"We needed to show our character and prove that it is still possible for us to win the title.

"For us the only way that this can be described as a successful season will be for us to win a trophy, we want the Champions League and we still want the title.

"We must win something, a trophy now is very important for us and we are still in there fighting."
