Arsenal midfielder Santi Cazorla admits the attitude of Alexis Sanchez has lifted everyone at the club.

It isn't just on the pitch that he fights, desperate to improve his talents. On the training pitch, his work-rate is extraordinary too.

"Alexis is as intense and annoying in training as he is on the pitch," Cazorla told Sport. "He's so into football that he doesn't want training to finish.

"Sometimes the manager is calling it off because training is over and Alexis is always kind of sad, because he loves to play football. His work ethic is a really positive influence for all of us."
