Saturday was the second time in a month that Donnarumma had been caught out at a corner, only to blame the referee rather than taking responsibility himself. He was incensed when Bournemouth scored following a corner as Donnarumma felt had had his arm held by David Brooks while waiting for the cross to come in.
It did not impede his ability to reach the ball but he still bungled the punch, leading to Tyler Adams pouncing on the rebound. Donnarumma shouted at referee Anthony Taylor after the goal was given and then again at half-time, but there was little sympathy overall for the Italian given his poor-quality punch.
That play likely alerted Newcastle when they did their opposition analysis to Donnarumma's weakness in dealing with crosses on top of his head, and more clubs are likely to take note.
Donnarumma's role and reaction to Barnes’ winner, meanwhile, overshadowed another questionable moment from the goalkeeper, as he nearly conceded a goal in the first minute after ill-advisedly playing a short pass to Foden on the edge of his area, leading to Joelinton mugging the England midfielder and Barnes firing straight at goal.
