Arsenal boss Arsene Wenger was confronted by a fan during defeat at Southampton. The Daily Star says the supporter was escorted out and arrested after running in front of the away bench and appearing to gesture at the Gunners boss in a second-half flashpoint.
Southampton believe it was an Arsenal fan who was sitting among home supporters.
But Wenger attempted to play down the incident, saying: "It was a young boy, yes. I think he was Southampton fan. He was not aggressive at all.
"I don't think he said anything. Honestly, he was not aggressive."
