Wenger said: "Not a lot happened!

"We're just upset, maybe they were being provocative. Nothing more."

Wenger was disappointed his side failed to earn even a draw.

"We came back in the game in the second half and should have come back to 1-1," added the Frenchman.

Wenger could not resist a jibe at the 'professionalism' of the Greek side.

"They tried to gain time, they dived," he said. "It was the usual thing you expect."

Henry admitted he "went mad" at the final whistle but blamed it on Panathinaikos' "disgraceful attitude."

He said: "I've never lost it before like that. The worst thing about it was that Michaelson was laughing.

"What they did was disgraceful. It was too much. I got a two-footed tackle but just got on with the game but every time we tackled they went down."

Wenger accepts that the Gunners' away form in Europe is a major concern, but he insists he has not given up hope of qualifying for the second group stage.

"I'm concerned about the goal we conceded. We have to defend better," he said.

"It is also a concern that we've lost six of our last seven away games in Europe, but other teams have bad records, like Juventus, who have not won away for two and a half years.

"We must win our two remaining home games now and I think we have the ability to do it. We can still get second place because not even Panathinaikos are qualified yet."
