Some of the responses are interesting and whilst none are 'incorrect' or 'correct' (they're just opinions), the questions I have are why are people so bothered about the money? It's not ours to spend, if United were willing to spend it, then why not?
Also, people kept bringing up neither when we need it for a central midfielder. I was talking purely about the left-wing, and if United have over £100m to spend and are willing to, then why can't we buy in both areas?
Another thing is if we agree Bale is a better left winger but Young is a better squad player, why should we choose a player who'd be less beneficial to the starting XI? Yes a good flexible squad is required throughout a season, but at the end of the day it's eleven v eleven in each game.
