A Sky Sports camera high up in the Arsenal stands shows Walker and Haaland walking off the pitch towards the tunnel. Gunners set-piece coach Nicolas Jover, who used to work at City, stood just off the halfway line.
As Walker left the pitch, Jover turned and walked over, offering out his hand for a handshake. Walker though, flung his arm in the air to reject the Gunners coach, with Jover appearing to aim verbals at him as he walked past.
That caused the City right-back to spin around, charge over to Jover and square up to him. Haaland also moved over to confront Jover, as staff members from both clubs also moved in to break up the trio.
Haaland, Walker and Jover continued to trade verbals even as they were separated. The Norwegian international continued to try to confront Jover, but was held back and eventually led down the tunnel.
@sensiblepuffin@Astrealix wasn't it Walker who gave Zinchenko a hard time last season after beating us? Guess he doesn't like it when he's on the receiving end.
