I'd swap him for Di Maria in a heartbeat, I think he's the perfect winger for us and our system and Van Gaal clearly wants goals from midfield, which he brings. He hasn't regressed quite as much as some believe, excellent pace and close control, excellent movement and work rate. I'm not sure what people are really looking for in a player these days?
One thing I don't understand though, is the mooted transfer fee. He signed a new contract in June, with an 150 million euro release clause still present. Why would Barcelona sell?
