Arsenal defender Per Mertesacker has hailed teammate Santi Cazorla.

Cazorla struck twice in victory over Aston Villa.

"You see he takes his chances with his technique and his feeling," the German international told Arsenal Player. "He is the perfect footballer. He has the technique to score goals and that's what we need after losing the last two home games.

"There was a bit of pressure but we are on a good run in the league so just needed to focus on that. It was a very important [result]."
