If you ask me, his problem is he started believing he was an elite player himself. I see him making the dumbest moves over again. Dribbling players near his own box or to or giving risky passes. I actually remember Cancelo suffered from a similar thing at some point in his career (he's playing his trade in SA nowadays)
Even I, who has never played football in his life, understands that the game has certain phases. Sometimes you need to play it safe and pass it backwards or sideways to remain possession. Even Dani Alves or Zambrotta knew that. Sick of tired of this guy. He's not even that good to begin with.
He's just a dumb dumb if you ask me. I hope City signs him for the 60m and we can ship this olive tree out.
