Arsenal boss Arsene Wenger admits Theo Walcott has toughened up this season.

Walcott struck twice for victory over Swansea City.

He said: "I would cut the 'little bit' off in your sentence and just say he's much more resilient, and not a little bit.

"He could have had a hat-trick, or even four, because he had another chance from Oxlade-Chamberlain. But he scored two goals. I think he's got seven now, that's quite encouraging."
