For us, Buendia has been terrific, really clever and subtle.
For them, Traoré, has there ever been a player so good at one thing and so naff at everything else?
System-wise - hard to judge, but one thing I will say is a danger of wingback systems is that they tend to have chances fall to them, and as we saw a bit with Cash today and definitely with Targett at Old Trafford that can be sub-optimal.
