Arsenal manager Mikel Arteta lavished praise on goalkeeper David Raya on Tuesday night.

Arteta spoke after his team beat FC Porto in the Champions League round of 16 on penalties.

Raya, who made a crucial save in the shootout, ensured that his team progressed by a narrow margin.

Post-game, Arteta said on Raya's mentality: “I didn't have to see him today, I was convinced that was going to be the case.

“You see him those first few days here, what he had to go through and how he did it with that composure.

“You look at his body language and the decisions that he takes, he doesn't get very affected. That's a key quality for that position."
