PSG's result has very little to do with having players like Di Maria and Draxler on the wing. Firstly Di Maria doesn't even really play on the wing, secondly we have two players of similar or perhaps better level in Özil (yeah, come at me knee-jerkers) and Alexis, and you see how much that's worth in our set-up.
PSG's result was down to an absolutely shocking, Arsenal-esque performance from Barça, and PSG playing well enough.
Gnabry may not be a world-beater yet, and of course he wasn't going to solve our problems, but that's the point; neither can Iwobi in such a set-up, he's destined to fail in a game like this with a set-up as horrific as that, so I don't really see the point in singling him out. That's the point. Gnabry I just brought up for kicks and because I think Gnabry and his qualities would suit us very well, Iwobi-Alexis-Gnabry would've been my first-choice team selection in league, and given that Iwobi-Alexis-Walcott was actually working pretty decently before Cazorla went down, Xhaka got suspended, Coquelin and Ox kept playing, and our team broke more than it already was.
@ronniec I wanted Draxler in January too. If Gnabry were still here and performing I probably wouldn't've cared too much but yeah, Draxler was a simple and obvious signing that we could've and should've made. But I don't see our reality being any different right now with Draxler, which is again the point, in fact I expect he'd probably be getting called a bust right now and getting similar criticism directed his way as Özil and Iwobi, as for a more advanced player in this set-up it's impossible to make an impact. Honestly, in such a set-up, we'd be better off with a Victor Moses type--or last night Welbeck--who is just going to put in a shift and really work in defence. The quality of Draxler or Iwobi is pointless if they're not going to get the ball in any kind of remotely threatening situation.
