Erling Haaland beat his fist to the ground in frustration as he was unable to keep the ball in play. The Manchester City No.9 got up and gestured towards Jack Grealish with anguish on his face after playing the ball to his teammate had not ended in a goal.
You could be forgiven for thinking the home side were struggling if taking that snapshot in isolation. When placed in the bigger picture, it was a reaction that summed up the chasm between the two Manchester clubs that shows no signs of closing despite grand overtures from Manchester United about a fresh start and £225.4m spent to back their new manager out.
Haaland's frustration came with City 3-0 up before half-time but hungry for a fourth, Pep Guardiola's champions bringing all the energy and verve (and quality) to this game as they repeatedly pummelled a lifeless United. The away end was visibly emptying by the time, a few minutes later, Haaland was supplying Phil Foden for the fourth goal to pile on the embarrassment for Erik ten Hag and his players.
