KYLE WALKER angrily confronted referee Michael Oliver in the tunnel to continue his protestations at Arsenal's equaliser against Manchester City.
Riccardo Calafiori cancelled out Erling Haaland's opener with a stunning left-footed from outside the box in the 22nd minute.
Walker and his team-mates fumed at Oliver as they believed the free kick leading up to the goal had been taken quickly.
The England international's frustration stemmed from him being out of position as a result of Oliver's calling of him over.
And he seemingly reminded the veteran ref of during the half-time interval.
Walker's half-time protestations to Oliver weren't picked up by Sky Sports' cameras.
But it was seen by BBC Sport reporter Simon Stone.
He wrote on X: "Kyle Walker making his point to Michael Oliver in the tunnel at half-time."
