The record books will show that this game slipped away from Manchester City in the 56th minute, when Mohamed Salah scored and left them needing four second-half goals.
In reality it was probably over some 26 minutes earlier in the evening, when referee Antonio Mateu Lahoz informed Pep Guardiola he would spend the remainder of the game in the stand. There is a reason an orchestra has a conductor.
He does not play a solo, not even an instrument, but he regulates those who do. He sets the tempo, he harnesses the energy of the group. That is what Guardiola does for his players. In his absence, the technical area sat empty, forlorn.
