Patrice Evra claims Manchester United's superior mental strength will give them the edge over Arsenal on Sunday.
The defender is in confident mood ahead of the Emirates showdown against their closest rivals in the race for the Premier League title.
The Frenchman criticised the Gunners back in December for being 'a football training centre' that does not win trophies and a 'club in crisis'.
And now Evra has stuck the boot in once again ahead of the crunch clash with Arsene Wenger's men, who are nine points behind United with just four games left.
He told the Daily Star: "I don't know (about Arsenal's collapse) but this is not my business.
"My business is Manchester United and I know we just have the strong spirit, the strong mentality.
"Every time we pull on the shirt, you know we respect history. It doesn't matter if we play well or bad, we have to keep at it 100 per cent.
"That's what Manchester United are doing every year.
"I don't say it because I'm playing for Manchester United but it's amazing.
"When you arrive here they tell you the story, you watch it on DVD and you learn. I think every young lad has to do this. When you know that story of the club you play with more respect.
"You know that every time you get that shirt, you have to do your job because the people have played before you did it and you have to do the same."
Evra is aware the North London club have beaten United just once in the last 11 meetings and he is confident that a win at the Emirates will virtually guarantee them a record 19th crown.
He added: "We can take a big stride towards the title and this is why you play for Manchester United.
"Arsenal lost to Bolton and they want to show their fans they can still win the league.
"That's why I think they will play as if they have nothing to lose, you know, and they will be very dangerous.
"We always have a big game, another final, but I think if we win there, we can win the title race, but it will be a massive race."
