Arsenal legend Thierry Henry was involved in a row with one of the Gunners' own fans after Sunday's defeat at Swansea.
The 34-year-old has rejoined the Gunners on loan from the New York Red Bulls and came off the bench during the 3-2 loss at the Liberty Stadium.
And after the game, the Frenchman had a heated exchange with one fan before storming off the pitch.
uoted in several national newspapers, a Gunners source said: "Thierry had encouraged his team-mates to go and acknowledge the fans and show their appreciation for the people who made the long journey to Swansea.
"Unfortunately, one or two of them had a few things to say and expressed their disappointment.
"One in particular was shouting: 'Where is the heart and the character and the fight?' Thierry shouted back: 'Get behind the team and support the players and don't be negative.'"
"You are always tempted to start him," said Wenger. "When he comes on the pitch he gives us a lift. He was dangerous again."
