While Iraola knows his side can compete when at their best, he acknowledged the Gunners' quality.
Pre-game, Iraola said: A lot of things that they do very well.
But I would say especially they are elite level football players, but their work-rate, their discipline, sense of collectiveness is like if they were not elite level.
They have this humbleness to do all the stuff without the ball, recovery runs, and that makes them very difficult to beat.
They don't concede chances, they don't concede goals.
They are the team in the league conceding by far the least everything less corners, less goals, less chances and I think this is because they have a very good work-rate.
Probably in comparison to other big clubs, that also have very, very good players. But I think they are playing really well."
