Manchester City boss Pep Guardiola was tightlipped over a post-whistle clash between his players and Arsenal staff.
After their 1-0 defeat at the Emirates on Sunday, Erling Haaland and Kyle Walker were seen in a heated confrontation with members of Arsenal's bench.
"I know what happened but I won't say anything," Guardiola said with a smile.
"They [Arsenal] know it," he added.
As the players were heading down the tunnel, Walker turned back to confront Arsenal set-piece coach Nicolas Jover, with Haaland soon following him. Jover had previously worked at City.
Eventually several players and members of staff from both clubs acted to separate them. Jover was taken away from the melee by Bukayo Saka.
