Was Alexis Sanchez laughing on the bench after being substituted against Liverpool?

The Gunners were put to the sword by Jurgen Klopp’s ruthless team at Anfield yesterday.

Roberto Firmino, Sadio Mane, Mohamed Salah and Daniel Sturridge all scored as the Reds ran riot against Arsene Wenger's hapless team.

The game was Alexis Sanchez’s first of the season - and he looked very frustrated throughout the match.

He’s been constantly linked with a move away from the north London side this summer after entering the final year of his contract.

And many Arsenal fans thought the Chile international was laughing at his team’s situation when he came off the pitch in the 62nd minute.
