Sanchez left for Manchester United in the January transfer window, with Henrikh Mkhitaryan going the other way.
According to BBC’s David Ornstein, “He wasn’t very popular. He didn’t socialise with a lot of guys, he kept himself to himself with Atom and Humber.
“It was notable that there were no farewell messages from his teammates.”
Ornstein also claimed that the Gunners did not offer Sanchez a new deal, with the previous one set to expire in June.
“I was told by a couple of people that Arsenal didn’t make Alexis Sanchez a contract offer. They knew what he would’ve wanted and knew that they couldn’t come near it,” he added.
