Don't let the facts get in the way of your argument ?! The facts are that he came on and contributed absolutely nothing other than give the ball away. Not one chance created or shot as far as I can recall in thirty minutes on the pitch. Another fact is that on the whole, and I am prepared to give him time, he was average to poor at best last season for reasons other people seem to think was down to Pellegrini / the system, excuses, excuses. He started the season OK, no more no less, and all was fine when we were winning, but he has been very poor and back to his worst in the last two months. I cannot recall a single game this season where he has turned the match in our favour, not necessarily a problem if others are doing it, but we always seem to have to rely on Ya Ya, Aguero, Silva, De Bruyne ( who in my opinion has also been poor on the whole this season ), Fernandinho, etc, to actually take a game by the scruff of the neck. His technique at times is utterly wretched, another fact. I hope he proves me wrong but in my opinion for £50m we should be getting something more than a debatable upgrade on Navas. We shall see how the season pans out but I believe his time is almost up and Guardiola wont stand for it much longer. Nothing would please me more if I am proved wrong.
