Manchester United captain Nemanja Vidic admits the club have become 'obsessed' with beating Barcelona in the Champions League.
The Red Devils could face the Spanish champions earlier than anticipated after last night's Group C draw against Benfica, with Sir Alex Ferguson's side looking set for a second place finish behind the Portuguese outfit.
That would leave the door open to a possible tie against the tournament holders after last season's 3-1 win at Wembley, and Vidic believes it is now verging on an obsession to beat Pep Guardiola's side.
"Yes [it has become an obsession], but we played a semi-final against them [in 2008] and won that, so that is something," said the Serbian centre back.
"If you look at the two games in 2009 and 2011, the way they played, they were the better team in both, and they deserved to win in both. But this is a new year, with new challenges.
"We have played them in pre-season, beating them this summer, and twice in the Champions League in the last few years, and I think we have learned some things along the way."
Vidic continued by stressing that United have stuck to their own principles despite the defeat in May, and won't be changing their football philosophy to match that of the Catalan club.
Instead, Ferguson's men will stick to their own philosophy, and simply look to improve in areas they are already strong.
"We have not changed the way we play to be more like Barcelona. They have their own way of playing and so do we. Yes, they have beaten us twice but the success we have had is not something you should underestimate. We have played in three finals in four years," he added.
"We have our own way of playing and we are Manchester United.Yes, we can improve and we will have to if we want to beat the team who were champions of the world last year.
"It's not about revolution, about doing things differently, it is just doing the same things better. We cannot copy the way Barca play. The way they play, compared to English football, is alien."
