He's an explosive player. His acceleration is excellent and he's not slow at all. Granted, he's no Bale but he's not all about his pace. He's also built like a tank so he doesn't get shrugged off the ball easily. He has weak points, but not being quick enough isn't one of them.
With everything around Memphis suggesting that he's coming that's the only thing I'm sure of. I think he's going to be a player we wished we would've gotten in 3 years time if we kept Nani and Young for another season.
I think one of Young/Nani will be sold to buy Memphis. Nani's got a contract untill 2018, it's his wages which are a problem. If anything, this season should make it easier to offload him. That he was loaned out in the first place makes me think he's a player which isn't suited to van Gaal's ways sadly (I actually like Nani). I don't think van Gaal wants to get rid of Young after this season. I have absolutely no idea though.
