Gunners attacker Theo Walcott disclosed that Alexis Sanchez has been training a lot since he arrived at Arsenal in the summer transfer window.
The South-American scored two goals again as Arsene Wenger's side beat Burnley 3-0 at the Emirates on Saturday. Alexis Sanchez has netted seven goals and made two assists in the Premier League this season after his move from Barcelona.
And Walcott, who came off the bench as a substitute in the 80th minute of the match said he has been impressed by the Chileans' extra training at Arsenal.
“In training he doesn't even want to do recovery days,” Theo Walcott told talkSPORT. “That’s how much he loves football.
“All the guys have told him he needs to chill out because, at Christmas when all the fixtures come along, it’s going to catch up with you.
“He doesn't care, he just wants to play and win. He’s a good leader, and something that we haven't had in the Arsenal team before. He’s a dream to play with.”
