Arsene Wenger was furious with referee Peter Frojdfeldt Ryan Babel after a penalty-shot won the match against Liverpool on his side.
Wenger, clearly emotional in the wake of his side the Champions League elimination, could not understand why Liverpool's Ryan Babel received a penalty.
"It's a bad decision, I think, the referee, but there was still a lack of concentration in the immediate aftermath, he went 2-2. They found in the box of Babel straight from kickoff, and that's where the concentration dropped a little.
"The punishment decisions made the difference, I do not know - I think we have to live with that, and for seven, eight weeks in football, we have to swallow sometimes, which is not swallowed, but and this is how we must live with Who at the moment.
"It is very difficult for me to understand, but we must also accept that and accept that in a game like that in which we had so much control, we were too naive, and we lacked a little maturity defensive."
But midfielder Ryan Babel saying after the game, is it a penalty.
"I think so, yes. It kept me a little and tried to take the chance of me. At the end, I did not have the opportunity to reach the ball. If they take that away from me, I think it was a penalty. "

Wenger: Penalty, it's a bad decision
Peter Crouch leaving Liverpool ?

Peter Crouch accepts it is likely to consider leaving Liverpool in the summer to get regular first team football.
The England striker scored an impressive goal in the opening 1-1 Premier League draw with Arsenal Emirates Stadium on Saturday.
However, Crouch feels he is likely to be back on the bench Tuesday night Anfield for the second leg of their Champions League quarter-final with the Gunners when leading scorer Fernando Torres expected to lead the attack again.
Liverpool have offered the 27-year-old, who arrived from Southampton in £ 7million deal in 2005 of a new contract.
Yet Crouch, England, who has 25 caps, has left its future may well lay elsewhere if it can not hold a first team place.
"I would have liked to stay, it is a fantastic club and I like everything about him, but I learned to be realistic," said Crouch, who has only seven Premier League starts this season.
"If I want to have any aspirations to play for England, or the pursuit of my career, then I have to read - and this does not seem to be the case at this time.
"I will have to watch - but it is certainly something that I do now, I will do that at the end of the season."
Crouch, however, insists on its present course of Liverpool on aid to progress in Europe.
"At the moment, I am concentrating on something Liverpool to win and play a role in the end of the season," he said.
"We have a Champions League run-in now and it's exciting for us, and all my efforts are concentrated on that." (*)

Wenger frustrated by ruffled Arsenal

Arsenal FC manager Arsène Wenger said his side did not get the result their performance merited and lamented the "lost composure" among his players following Liverpool FC's equaliser. The 1-1 draw in London has, according to Wenger's opposite number Rafael Benítez, left this UEFA Champions League quarter-final wide open – with the Merseysiders in a particularly "good situation" going into the second leg.
Wenger says, "I feel we were not well rewarded for what we produced tonight. To finish a game like that at 1-1 is very disappointing, but we delivered the performance we wanted and overall we had chances to win. Liverpool created very little and the whole second half was played in their half. I cannot fault the players and we were unlucky in a few circumstances – I don't know how the ball didn't go in when it hit Nicklas Bendtner. It's difficult because Liverpool defended very deep so it was hard to find space. In a game like that you do not make 20 chances, you create four or five and we were punished on the one they had.
