The 20-year-old joined the Premier League champions in January but was immediately loaned back to Selhurst Park for the remainder of the campaign, and he helped his side to a play-off final win over Watford.
Monday's man-of-the-match display was Zaha's final game for Palace and his team-mate Wilbraham thinks he will do well at Old Trafford.
"He's going to a great club," he told Sky Sports News.
"Wilf's done unbelievable for us this season and he's been outstanding in the play-offs as well but he's going to go to Manchester United and try to burst into their team, and he's more than capable of doing that.
"If the chance came for us to have him back on loan, we'd snap at the chance but we'll just have to wait and see what happens. I think Wilf's good enough to get in the team to be honest, he's a great player."
Wilbraham also spoke of his delight at Kevin Phillips' winning penalty against Watford and says that he hopes the veteran striker stays at Palace for another season.
"I don't think I was that nervous because it was Kev," said Wilbraham.
"He knows what he's doing, he's been there and done it before but it's a great penalty and once that went in, the feelings were unbelievable. We just had to see the game out and we did that well.
"I hope he does, he's a great professional and he does everything right. If he's playing next year, to be 40 and playing in the Premier League is a great achievement. Everyone hopes he will stay we'll just have to wait and see what happens over summer.
"I think it's important for the group of players we've got to stay together. When I was at Norwich we kept a good group of older players and just added some young hungry players and I think that really worked well in our season at Norwich when we finished 12th," he added.
"I think people are going to say we're favourites to go down but in the play-offs you saw what we did; we frustrated some good footballing teams and then caught them on the counter-attack and that's what we'll probably have to do again next year.
"I think we've got some great team players and a good team spirit and togetherness and I think that's half the battle going into football matches."
