Chelsea manager Carlo Ancelotti believes his side have resolved a small problem after they defeated fellow title contenders Liverpool on Sunday.
The Blues endured their first loss of the season last weekend against Wigan and then struggled past Apoel Nicosia in the Champions League during the week.
After the victory over the Reds, Ancelotti said his team had recovered from a small bout of mediocrity.
"In Italy we usually say, 'It's the same the world over'," said Ancelotti. "It was not pressure. We lost one game and played badly for a second match but we worked hard to find the problem and resolve it.
"After this match, we've shown we've resolved our problem. It was not a big problem.
"It was an important win. It's normal that it was difficult because we played a strong team. Above all, the match was difficult."
Ancelotti added that he was happy with the way his team controlled the game.
"We maintained good control during the match. First half, it was a match with a lot of balance. Both teams kept good control of their defensive positions," he added.
"The second half was different. We scored the first goal and had an opportunity to counter-attack. They put a lot of pressure on our midfield and wanted to draw but I think we deserved to win because we did a very good job during the 90 minutes.
"I know we did what we prepared before the game and, for this, I'm happy. We wanted to avoid free passes for Steven Gerrard because he's a very dangerous player. Michael Ballack, Michael Essien and Frank Lampard did that job fantastically.
"They used the right side to attack but, on the left, we did a good job."
