Why? You guys have Bolasie who when gets going is hard to stop.
YALA is good, but Wilf is better. Besides, they generally play on opposite sides. All depth is good depth!
Btw we all slagged Moyes when it came to Zaha but Zaha hasn't done much since signing for Cardiff. Few reported that he started believing his own hype and stopped working hard which may or maynot be the case but at least from what he showed at Cardiff he needs a loan move before starting regularly for ManUtd.
He's actually been Cardiff's most promising attacker a number of times, it's just that nobody gives him ANY support. They maroon him out on the wing and ask him to do something, ANYthing, and occasionally he does but most of the time he's crowded out. Doesn't help that KTC behind him tends to cut inside onto his stronger foot so they become really narrow down that flank. But Cardiff fans now hate him after he didn't play particularly well against Palace - like the rest of their entire team - and accused him of not playing with passion or somesuch bullshit. Meh. It's not been a successful loan.
Or maybe his confidence was shot dead when he signed for one of the greatest ever manager and ended up playing for a dull Scott who loves to play with "Don't lose" mentality.
He's a pretty confident guy. I'd say he's just disappointed that he didn't get a chance to work with Ferguson and then was frozen out because Moyes didn't like his somewhat cocky attitude and wanted to trust senior players. By the time it emerged the senior players weren't up to it, Moyes had already decided he wasn't going to play Wilf because Zaha was getting restless over his lack of playing time. And thus the loan. It's a sticky situation.
EDIT: And I don't believe the "believed his own hype" thing for a second. This is a man who's been touted as being a huge star since he was a kid. It never stopped him working hard before, I doubt it would stop him as soon as he gets the biggest opportunity of his life.
