John Terry believes Chelsea have what it takes to win at Manchester United for the second successive season and put themselves on top of the Premier League table.
Last season goals from Joe Cole and Didier Drogba secured a crucial victory as Chelsea went on to win the title in Carlo Ancelotti's first season in charge. And Terry thinks they can repeat the feat on Sunday.
Everyone thought Chelsea have blown their title hopes after a disastrous run before Christmas, but no side has won more league points than Chelsea since the turn of the year.
"Each season you know you are going to hit a bad spell and it is about how quickly you can get out of it," he told the Daily Express.
"We got out of it very quickly last year, and have taken a little longer this time - but once again we are right back in the frame.
He said about the title success of 2009-10: "We ran away at the top very early and people were saying it was over after 10 games, then we had a blip.
"But we picked ourselves up and hit some good form towards the end. It was probably the best form I have seen, with the results and the free-flowing play. The amount of goals we were scoring was incredible.
"We showed when we went to Old Trafford and won last year, which was the decisive game, that we could do it. There is no reason why we cannot do it again.
"There is nothing I want more than to bring back that trophy."
