Arsenal boss Arsene Wenger was left frustrated after their 0-0 draw with Middlesbrough.

The Gunners' boss was celebrating his 67th birthday as they fought for their seventh consecutive league win but an impressive performance from Boro goalkeeper Victor Valdes and a lack of creativity in midfield kept the game goalless.

Speaking about the performance, Wenger said: "I think I have a frustrated face and I am (frustrated).

"We had a lot of the ball but a lot of the ball in a modern game is not enough to win the game.

"I felt that with 75 per cent of the possession, we did not have our usual pace and not enough sharpness in our movement.

"The first 25 minutes were quite satisfying but Middlesbrough came back in the game with a break.

"In the end we could not do enough to win it but at least we were concentrating enough not to lose it.

"We could have lost the game in the first half, we lacked a bit of creativity."
