Michael Owen insists that Manchester United will fight to the bitter end in the race for the Premier League title.
United go into the final day of the season as underdogs, with Carlo Ancelotti's Chelsea side in prime position to take the crown.
The reigning champions will have to secure victory against Stoke and hope that the Blues drop points at home to Wigan.
But Owen, who will be forced to watch from the sidelines due to injury, says that the Red Devils have not given up hope.
"You have got to believe," he told The Sunday Telegraph.
"Everyone says the same thing and it almost gets boring but you can only do what you can do.
"We have had opportunities to still be in the lead but I'm sure Chelsea would say the same. This is the position we're in and we can only affect our game.
"If we're winning comfortably after an hour and look like we're going to get three points and we increase the pressure by even just one per cent it is worth doing. We have to win.
"It'll be an interesting day. If Chelsea go and score two early it'll be a bit of an anticlimax but as long as we are still in it, we'll be fighting."
United boss Sir Alex Ferguson thinks his side has suffered a lack of penetration due to injuries afflicting Owen and star striker Wayne Rooney.
The 30-year-old former Liverpool man admits that being forced to sit out the climax of the season has been frustrating.
Owen added: "It's nice to hear the manager talking about me like that.
"I was really pleased with the season as a whole. There have been some great highlights.
"But in saying that I wanted to be fit for these last few games, that has been the frustrating bit.
"I think I was fit for 43 of the first 44 games. I only missed Sunderland at home with a bit of a tight groin.
"I thought everything was going great but whether it was the Wembley pitch or whatever, it unfortunately ended my season.
"I suppose if it was just me I wouldn't be thinking anything of it but there have been a few injuries.
"I remember England played on it a few days later and there were another few with muscle problems. It's frustrating, obviously."
