Chelsea boss Carlo Ancelotti says Didier Drogba was the game-breaker in yesterday's FA Cup semifinal win over Aston Villa.

Drogba struck the opener for Chelsea in the second-half of their 3-0 triumph.

"It was a difficult game, totally different from the last game when we won. We played not so good in the first half because we played without intensity, without pressure and left a lot of space and Aston Villa was really in the game," said Ancelotti.

"They played well with good intensity and we were lucky to stay 0-0 in the first half, second half was totally different because we put in more intensity and pressure, and scored three goals, it was really better in the second half.

"I think the key of the match was the first goal, of Didier. He scored 32 goals, he maintains a very good opportunity to score and is working very hard for the team.

"For him it is not so important to play from the beginning, when he comes on the pitch he scores. I have very good options in this moment because all the strikers are in good condition."
