Arsenal manager Arsene Wenger lauded Theo Walcott as a "completely different player" after the forward continued his impressive start to the season.
Walcott netted his third Premier League goal of the campaign as Wenger's men claimed a 3-0 win over Chelsea on Saturday.
"You cannot question his performance," Wenger told a news conference.
"But I believe more the change in Theo Walcott is his attitude to this season. He's ready to fight, commit and straight away he gets the crowd behind him.
"Theo Walcott of that stature is a completely different player."
"I'm hungrier because I know I don't have 20 years in front of me," the Frenchman said.
"Also I feel more responsibility, you're not 20 years somewhere and you don't care about things.
"I'm more conscious of what Arsenal is all about so I think the weight of keeping people happy and making people happy is heavier than when I arrived."
