Chelsea boss Jose Mourinho says Didier Drogba and Loic Remy give him plenty of options to choose from in attack.
This time last year, the Portuguese was quoted as saying that he lacks striking options in his squad but it didn't take long for the Blues to rectify the problem.
And with 54 goals scored in the Premier League, Chelsea have the best offensive department in the country.
"Didier [Drogba] is giving us a lot," Mourinho told reporters during his press conference.
"It doesn't matter on or off the pitch, or if he's playing five minutes or more than that. We cannot expect him to be running, getting behind defenders and being very fast because as you know time flies.
"He gave us what we needed today. We thought we were going to be dominant, and they were going to be defensive.
"We needed a target man in the middle of their central defenders that could give more freedom to the other players. He did that for us.
"When the game became broken after they scored, Villa thought they could win and the game had more space.
"They brought their defensive line a little bit closer to the midfielder; [Loic] Remy came on and obviously is faster and has more mobility. He gets behind defenders so we have to try to read the game and make decisions for the good of the team."
The Blues opened a seven-point gap at the top of the table after Manchester City's surprising result against Hull City.
But Mourinho says seven points can be easily cancelled out.
"In another country I would say [the lead] was fantastic, but in this country I would say it's nothing," he said.
"Every game is difficult, anything can happen. Seven points means seven points. We have 14 matches to go, 42 points to play for. We have a lead of seven and I think it's nice.
"Let's try to win the next game. If we do we will have a seven- point lead with 13 matches to go. Let's go step by step."
