Sanchez has featured in all Arsenal’s Premier League matches this term scoring 14 goals in 23 outings for the Gunners in all competitions and the 28-year-old energetic attacker has taken time out to explain how he keeps fit.
“I have always been like this,” he told Arsenal Player.
“My career won´t last forever and I am aiming to be one of the best players in the world. I want to do my best and be professional until my career ends.
“I enjoy football a lot, I always wanted to be one of the best players in the world and I´ve been saying that since I was a little boy,” Sanchez told Arsenal Player.
“I will slow down after I retire, but for the time being I will carry on like this.
“I just try to train well, sleep well and be professional at my job. There´s no much of a secret to it.”
