Alexis Sanchez feeling

The 27-year-old was substituted after 104 minutes of the match at MetLife Stadium in New Jersey - which Chile went on to win following a penalty shoot-out - in the wake of a heavy tackle by Gabriel Mercado.

After the match on June 27, Sanchez posted photos on his personal Twitter account of a badly swollen left ankle.

The Chile forward followed those on Thursday with updated images of the heavy bruising which has since developed while he recuperates on a break in New York.

Sanchez added on the social media site: " Fourth day of my vacation, locked up in the hotel bored hahaha...

But I'm already much better."

The Gunners forward then made another post, saying: " YOUR BODY CAN ENDURE ALMOST EVERYTHING..

IT IS YOUR MIND THAT YOU HAVE TO CONVINCE"
