Arsenal manager Mikel Arteta congratulated Aston Villa after their win on Tuesday night.
Villa claimed a 1-0 victory over the Gunners to move out of the relegation zone.
"Villa gave absolutely everything and perhaps we lacked a little bit of freshness," Arteta said.
"Congratulations to Villa because they were put under a lot of pressure and they managed to win the game. We were in some really good positions but we didn't manage to deliver the ball.
"Emotionally and physically it's been a very demanding week but I saw a team whio wanted to fight until the end. I'm not disappointed about the attitude - I know where we are in certain areas and where we need to improve more. We will get that."
