Gareth Ainsworth says his side must focus solely on beating Torquay and not worry about how the other results around them are going until after the game.
Wanderers must win at Plainmoor to stand any chance of staying in League 2, and Ainsworth believes there could be one more twist still to come.
“The lads know now that we’ve got to go down there and win,” Blues’ boss told Chairboys Player. “We have to do that, there’s no draw, there’s no defeat - we can’t get out of this without a win.
“They know what’s on the cards, they know what they’ve got to do, and maybe just maybe with a potential upset in the other two games we can do this.
“I’ve envisioned us coming home on the bus celebrating, I’ve envisioned all the fans celebrating with us at Plainmoor, and I’ve got to keep those visions at the forefront of my mind. I’m really looking forward to the game and I know the boys are champing at the bit.
“There’s going to be a great Wycombe following down there as always, and thank you very much for that you’ve been amazing all season, let’s do it together one more time!”
Wanderers’ fate rests on results going their way elsewhere, and Ainsworth revealed he has spoken to former Blues boss Gary Waddock, who could do Chairboys a favour when his Oxford side travel to Northampton.
Ainsworth said: “I spoke to Gary, we speak anyway we don’t live far from each other and we’ve always kept in touch.
“He was the first person to ring me when I got the job 18 months ago to wish me good luck, which is the measure of the man.
“Gary would want to win this game no matter what was on it, even if it was a nothing game he’d want to win it.
“There is something on it and obviously we’re good friends and we’ve been around together for a long time. If he can do me a favour I couldn’t think of a better guy to do it.
“The Wycombe connection with Gary and the Oxford connection with Chris Wilder, it seems written somewhere doesn’t it that something might happen.
“Don’t discount Mansfield though, they’re going to want to win against Bristol Rovers. They won’t want to go into the summer with three consecutive losses and have to wait three months before they can put it right.
“Whatever happens, we have got to do our side of the bargain!”
