The point is Iwobi is literally being sold for £20m + add ons and this lad is coming in on loan for basically nothing. Cornet will be a depth player for us and play most his games at left back, according to some Iwobi is the second coming of Kevin De Bruyne. The reality is on the wings, where Iwobi plays, Cornet is verifiably just as good as Iwobi if not better as he can actually score, is more versatile and is 100% on far less wages.
Most logical people would take them in a straight swap, nevermind getting a £20m profit for us. Again no one is saying Cornet is very good, or that good at all, he's just better than Iwobi who's utter crap.
