Arsenal star Theo Walcott has revealed that summer signing Alexis Sanchez does not rest even on recovery days and has urged the Chilean to "chill out."

The 25-year-old joined the Gunners from Barcelona after he was made aware by the Catalan club that his services were no longer required at Camp Nou. Since making a switch to the north London club, Sanchez has been in fine form and has already scored seven goals from nine league appearances.

Arsenal's club-record signing failed to adapt during the busy schedule in December last season. The Chilean international will be involved in Christmas for the first time in his career as his former clubs had winter breaks during the festive period.

The England international believes Sanchez could suffer a burn-out during Christmas if he avoids taking a break on rest days.

"In training he doesn't even want to do recovery days. That's how much he loves football," Walcott told talkSPORT.

"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," the English forward concluded.

Meanwhile, Walcott made his first appearance for Arsenal since January during his side's 3-0 victory over Burnley. He sustained a knee injury during the last season's FA Cup clash against Tottenham Hotspur and was out of action for the most part of this calendar year.

Walcott even missed the summer World Cup in Brazil. However, the forward came on as a second half substitute in the final quarter of the game at the Emirates over the weekend. The Gunners manager Arsene Wenger has expressed his delight after the 25-year-old returned to the first team on Saturday.

"It's good I could give him 12 or 13 minutes today when the game was nearly won. It's good that his decision making and movement are good - he just needs to get used to competition," Wenger told Arsenal's official website.
