Per Mertesacker was delighted for Arsenal skipper Robin van Persie after his double against Sunderland.

The Germany defender is hoping Van Persie pens a new deal with the Gunners.

"We are very happy to have him here with us," Mertesacker told Arsenal Player.

"He can score every time in the game - right foot or left foot. He is unbelievably important for us in our game. If he scores goals we will be successful.
