Although Leno's mistake in the Europa League group stage caused Arsenal to lose the ball, David Luiz backed the German goalkeeper in an interview.
In Arsenal's quick game against Vienna, Leno's passing error in the penalty area allowed his opponent to seize the opportunity and score.
Luis said: "I think Leno played very well. Part of our game philosophy is to attack from the backcourt. This is normal. You always want to break the opponent's press when you attack, and then the forwards will Play easier."
"So, you can count, how many times did this kind of game work? But Leno only made one mistake. This is part of our game philosophy. Leno is very good and he gives us a chance to follow He is trying to help us."
"This is a difficult game. We are facing a good opponent. Their competition is very intense. I think this opening is good for us because we can understand the future of the game."
"The opponent played well, but so did we because we stayed calm and controlled the game in the second half while finding a way to win."
