Chelsea captain John Terry has revealed how Aston Villa's players were left fuming after their 7-1 hammering by the Blues at Stamford Bridge.[LNB] Terry, who is preparing to play his fifth FA Cup semi-final for Chelsea when they take on Villa at Wembley tomorrow, was told how much the defeat hurt Villa's players by former Stamford Bridge midfielder Steve Sidwell.[LNB]The England defender has now warned his team-mates to erase all thoughts of the 7-1 success from their minds when they face Villa once more.[LNB]"The one thing that all us players have got to get out of our systems is the recent result against Villa," declared Terry.[LNB]"Before we beat Manchester United last weekend we talked about how determined we were not to let them do again what they did to us last time we went to Old Trafford, and it's 100% certain that will be Villa boss Martin O'Neill's approach.[LNB]"I've spoken to Siddy (Sidwell) since we beat Villa at home and he was already talking about the semi-final. He told me that Villa were fuming over the way that they got beaten and the way they played.[LNB]"It is going to be a totally different game. It is a bigger pitch at Wembley and they will probably have one or two more players back from injury as well, so we need to make sure when we go in to the game we forget what has happened recently and approach it the way we normally would."[LNB]Chelsea coach Carlo Ancelotti remains focused on winning the double to make up for the hurt of missing out on the Champions League.[LNB]The Blues were eliminated from the competition by Inter Milan, a defeat made worse by the fact that the Italian side are managed by former boss Jose Mourinho.[LNB]Ancelotti immediately told his side the league and cup double was the priority and, apart from a 1-1 draw with Blackburn straight after the Milan setback, the Blues have responded in style.[LNB]They hammered Portsmouth 5-0, sent Villa packing 7-1 and then defeated Manchester United 2-1 at Old Trafford to go two points clear at the top of the Premier.[LNB]"I never won the league and the Italian Cup," said Ancelotti.[LNB]"In one year in 2003, I won the Champions League and Serie A.[LNB]"It is in our mind to win the double. We are very close but nothing is decided, we have six or seven games and they will be very difficult because every team has an aim to win."[LNB]Chelsea achieved their 7-1 success over Villa without the services of Didier Drogba. The Ivorian striker was on the bench for the entire game as the goals rattled in.[LNB]Drogba started among the substitutes again against United last week but came on to hit a controversial 'offside' winner.[LNB]But Ancelotti is keen to make it clear that the Ivory Coast international will be in the starting line-up against Villa.[LNB]"Didier is an important player for us," added the Italian.[LNB]"It is important for players to think they can be useful if they only play 30 minutes of a game and he did this very well against Manchester United.[LNB]"He was strong when he came on the pitch, but he will not stay on the bench on Saturday. He will start from the beginning."[LNB]Victory over Villa will set Chelsea up nicely for Tuesday night's home clash with Bolton in the Premier League and Ancelotti already has one eye on that game.[LNB]"Now is a good moment for us and we don't want to come back and have a bad moment," he added.[LNB]"We want to do the best in every game for the rest of the season because we know it is important.[LNB]"At this moment the title is in our hands and we know we can play with strength if it is necessary. Every game in this moment will be tough. We have to pay attention to every detail because every game can be decisive."
