Neil Sullivan insists that there is no point in heading to Old Trafford to tackle the champions trying to win only a single point.
Our keeper says that entering any game with the mindset of feeling a draw would be a good result is wrong. He reasons that only in reflection can a draw be considered on its merits.
"You can't go into any game thinking we'll take a point," said Sully. "You have to go in believing or there's no point turning up.
"If you go out there thinking 'oh, a point would be good here' it is not positive. You can say that after the game when you look at how the game panned out, if you've been under the cosh, defended well and maybe got a bit of luck.
"You'd be happy with a point then, but you can't go in at the beginning of the game trying to nick a point.
"It's going to be a difficult task up there, but we are back in winning ways and playing well. It is one of those games you look forward to."
Sully agrees with the theory that Manchester United are a team that do allow the opposition to play a bit.
"They do, but you've still got to earn the right and try and stop them at the same time. They are difficult games and hopefully we can get something out of it.
"They've got lots of top quality strikers, so we'll just have a look at the team sheet when we get up there."
From a personal point of view, Sully once attracted rave reviews from Sir Alex Ferguson, the United boss once said some nice things about him during his time at Wimbledon.
"He did, at a time when we played them a couple of times in the Cup and we took them to a replay and managed to win. Around that time he was very complimentary, which was very nice."
