Patrice Evra believes winning the Premier League title with Manchester United this season would be more important than their three most recent successes.
The Red Devils are looking to make history by lifting the trophy for an unprecedented fourth time in succession and remain very much in the hunt despite being beaten by rivals Chelsea last weekend.
United, who were also knocked out of the UEFA Champions League by Bayern Munich in midweek, are currently two points adrift of the Blues ahead of Sunday's clash with Blackburn.
"No-one has won four titles in a row in the history of English football," said Evra.
"We have the opportunity to do it. That is why this is one of the most important titles for Manchester United.
"I have won three titles with this club. None of them were as important as this one."
United may no longer be in control of their own destiny but, with five games still remaining, Evra is staying upbeat.
"I am confident," he stressed. "I am not saying that for the fans or anyone else.
"It is what I feel inside and I hope everyone feels the same.
"We can do it. The important thing now is to concentrate on what Manchester United is going to do.
"It is not about Chelsea or Arsenal, it is about us. We have a mission to win every game. After that we will see."
Meanwhile, Evra played down concerns that he may be about to run out of steam ahead of the World Cup after making 43 starts already this season.
"People say I am playing a lot of games but that is not an excuse," said the France international.
"It has never entered my head. I need to fight until the end.
"I was shocked to lose in the Champions League, but I knew there were still other challenges.
"The first one is winning the Premier League. After that I will prepare for the World Cup.
"That is something for my country, and something to look forward to.
"But I live in the present and the present is Manchester United, and trying to win the Premier League again."
