VIDEO: Arteta talks about Gasperini's comments on David Raya

David Raya's goalkeeping heroics ensured that Arsenal were only held to a goalless draw at Atalanta on Thursday in a tough start to their campaign in the revamped Champions League.

"That’s a question for him but last year was already very impressive and really good, even with a different context. This season he has started exceptionally - the save he made against Villa, today he kept us in the game. That’s the reality. You need that from your keeper at this level. I’m really happy he’s in the form he’s in at the moment," Arteta told reporters when asked about Raya and the reactions he had caused to his rivals.

"It was a really tricky game emotionally because you are all man-orientated, so every action counts in your emotions. When we had certain moments that didn’t go our way, I could sense the team was a little bit about to lose the discipline this requires," he added.
