Wigan manager Roberto Martinez has assured Manchester United his side will not make it easy for Chelsea to win the title this weekend.
United's hopes of claiming a fourth consecutive Barclays Premier League title depend on Wigan denying current leaders Chelsea victory in their final game at Stamford Bridge on Sunday.
Wigan, having secured a sixth season in the top flight, have little to play for but Martinez has no intention of letting Carlo Ancelotti's men ease to victory.
The Spaniard said: "A strong performance at Stamford Bridge is an important way to finish the season. We are not going to just turn up and be another team at Stamford Bridge."
He added: "We will approach it in a manner where we want to hurt Chelsea on the day.
"It is going to be difficult but the players have huge belief that we can go to Stamford Bridge and make things very, very difficult."
The odds are against the Latics but they know from experience the Londoners are beatable having shocked them 3-1 at the DW Stadium in September.
Having never beaten one of the 'big four', Wigan were given little hope then but not only won, but also went on to claim surprise home wins over Liverpool and, last month, Arsenal.
Martinez added: "The Chelsea performance was really, really pleasing the way we stopped them from being Chelsea. We were the better side.
"We had a few chances in the first half and we got a goal from a set play. In the second half when Chelsea scored the equaliser I just felt it was a real test how we would react to that.
"To finish the game and win we got rid of that mental block that Wigan Athletic would never be able to beat the top four. We are going to approach it on Sunday in the same manner."
