The thing for Wing is he might score 5 screamers, but some other dude he's being compared to might score 2 in the box. That's a difference of three goals, which is great on paper but Wing might have less ability as a midfielder than almost every other first-team midfielder in our squad. This difference may ultimately might cost us 5 goals, as centre mid is extremely important. Also, how many shots does he miss/ give up possession?
He's the best striker of a ball we've had for years, no doubt about that, and if he was better at his no 1 job then he would be a cracking player.
One thing to consider though is long shots are a valuable asset against compact teams, who defend well, or who you can't break down as you get fewer opportunities in the box. So the goals he does score, could effectively be worth more, in some situations.
