Arsene Wenger accused the match officials of “killing” Arsenal’s chances against Bayern Munich on Tuesday, with the Frenchman considering his side to have been “unlucky” despite suffering a 5-1 defeat.
The Gunners entered a meeting with the German giants having suffered a humbling by the same scoreline in the first leg of their Champions League last-16 encounter.
That result, along with other struggles in the Premier League, led some supporters to stage a protest against Wenger prior to kick off.
A toxic mood was lifted slightly in the opening exchanges as Theo Walcott offered Arsenal a glimmer of hope, but the dismissal of Laurent Koscielny early in the second half proved decisive.
Wenger, though, believes that crucial call was wrong, with Robert Lewandowski offside leading up to the game-changing challenge and Greek referee Tasos Sidiropoulos conspiring to make a tough task impossible for the home side.
“I feel we produced the game we wanted and we are very unlucky tonight with some decisions which were very difficult to understand,” Wenger told BT Sport.
“We are 1-0 up, it's a 100 per cent penalty on Walcott, Lewandowski's offside, there's no penalty on top of that, you get the red card, of course that killed us.
“Overall it's difficult to understand what's happened. I still must say my team has produced a huge effort tonight and played very well.
“He is offside, Lewandowski, there is no penalty, on top of that he gives a yellow card, on top of that he gives after a red card.
“It's just not serious. When you see the importance of the games and you see an attitude like that I am absolutely revolted and sorry for people who come and pay a lot of money to watch this kind of game.”
Wenger has now seen his side exit the Champions League at the first knockout stage in seven successive seasons.
Those continental failings have contributed to the calls for him to step aside at the end of the season, but the long-serving manager believes there are positives to be taken.
He added: “I felt we were in it.
“You never know how Bayern would have reacted had we scored a second goal and at the end it finishes like that, it's difficult to take. And of course it looks very bad and doesn't reflect the quality of our performance tonight.
“I think once it was 2-1 down it was very difficult. You have no chance to qualify any more. That's not the part of the game I would like to keep in my mind, because I think the second part of the game has been spoilt by the referee.”
