Unai Emery has praised Nicolas Pepe for a "perfect" double against Vitoria on Thursday.

Down 2-1, substitute Pepe scored two free-kicks with ten minutes remaining to win all three points for the Gunners.

"Every new player usually needs time for adaptation," he said in his post-match press conference. "Pepe is a very good player and we believe in him totally.

"We are very happy for him and us because he has two goals from two set-pieces which were perfect. He trying last week with set piece shooting on the training ground and I was watching his shooting.

He is improving and tonight he has two goals, which are important for us and for him. He's continuing the adaptation in his process and as soon as he can adapt, that's better for us.

"The most important thing is the three points and that some individual players can improve, that they can take confidence for us and for them."
