Carlo Ancelotti believes a 'different atmosphere' this week will send Chelsea into Manchester United game full of confidence

Blues boss doesn't think Sunday's clash is decisive

Chelsea will entertain Premier League leaders Manchester United on Sunday in high spirits after a positive week of training, according to manager Carlo Ancelotti.

The Blues welcome back Frank Lampard to their starting eleven for the game against United, which comes in a crucial period for Chelsea.

Having missed a late penalty to win the game against Tottenham last week, Chelsea also travel to fellow title challengers Arsenal next weekend.

Despite being on their worst league run for over a decade and without a win in five games, Ancelotti is confident that his side have turned the corner.

"To play against Manchester United can be a fantastic motivation for us. We can use this game to move on from a difficult moment," the Italian told reporters on Friday.

"I think the difficult moment is finished, there was a different atmosphere in the training ground this week and I hope that in the game we are able to do our best.

"We trained well. We had the possibility to train with all the players and so the atmosphere was different compared to the last weeks - better."

Chelsea beat United in both league meetings last season as they marched to the Premier League title. However, their recent dip in form has seen them slip to fourth place, three points off top-of-the-table United who also have a game in hand.

Whilst Ancelotti admits that the game is important, he believes it is far too early to say whether Sunday's clash will be decisive in who picks up the Premier League trophy in May.

"Last year they were the most difficult opponents and were in the fight for the title until the last game. I think they will be the same this year.

"Now they have an advantage in the table and we want to use this game to improve our play and our result, and stay close.

"There are a lot of games, and a lot of teams involved at the top of the table thinking they can win the title. It is too early now to say it could be a decisive game. It is an important game, also for your confidence.

"If you are able to beat Manchester United as we did last year, it was good for the mentality, character and personality of the team."
