To be fair he did everything I was asking of him yesterday (i.e. was willing and ready to use his right when he needed to, was far quicker and more decisive with his actions and he did his bit defensively) and I think it made a difference? Kept his markers guessing and off-balance, and stopped the whole oppo defence getting back and getting organised as he tries to work an opening on his left.
I do think there's a very good player in there - my main gripe with him (and when I say 'him' I mean Raul and Emery) was always that he felt like a bit of a hush-signing to cushion the blow of ending up with Luiz after we lost Koscielny and Monreal, had to loan Saliba back to St Etienne, failed in a bid for Upamecano, and failed to move Mustafi on. (And potentially rinsed most of next summer's budget!)
