Chelsea boss Carlo Ancelotti admits his team can learn a lesson from Liverpool who recently defeated Manchester United 2-0 at Anfield. The Red Devils travel to Stamford Bridge in the knowledge that a win would put them above the Blues at the top of the Premier League.
The Italian claims his side must match Liverpool's workmanlike ethic to dispatch United.
"Liverpool played a fantastic match, a strong match, and put a lot of pressure on the pitch," he said.
"That's why they won. They didn't give United any possibility to play like they want to play.
"It was a good lesson for us because Manchester can suffer when there's pressure on their midfielders.
"I don't want to play against other team's weaknesses. We want to put our own qualities on the pitch.
"He (Ferguson) did a fantastic job with this team. For a coach to stay such a long time with one team is very difficult, not only in England but everywhere.
"In Italy it would be impossible, for sure. He's a very important man for the history of this club. United have a fantastic history and Ferguson is one of the most important men in this history."
