Young has been praised by some as one of our best players but yet had only scored 1 and assisted 1, I dunno about you but I'd rather someone who can do what Young can do and score 15+ goals.
If Depay came and got 15+ goals, I'd be ecstatic. However, as you know, there is a fair chance that he won't do it in the PL despite the fact that he did it in Holland. I don't think I want another Young without the 15+ goals, to use your example - although I'm not saying that's all that he is.
For me, the wide player I want us to sign isn't necessarily all about goals. Penalties aside, that could be taken by Coutois - Hazard is not a great goalscoring winger. However, he opens up the game for Chelsea in a way that their goalscorers cannot.
Moura, or Douglas Costa would get my vote, although I'm not writing off Depay - just saying I have some reservations.
