Arsenal boss Arsene Wenger paid tribute to Olivier Giroud after victory over West Ham United.

Giroud's goal finished off a classic slick Arsenal passing move as the France forward continued his fine recent form, with six goals in the last seven.

"It was a fantastic goal because it's a consequence of a fantastic combination just before and after. On top of that the finishing was great," said Wenger.

"Giroud is a boy who has played at 22 or 23 in division three (in France). He's come out and has become an international footballer.

"You need some mental strength to do that because there's no red carpet there. You have to work hard to get out there and get to the top - you need some special strength."
