However, he caught their eye for a very different reason – in one particular incident – during their 1-0 win over Leicester City on Wednesday.
And it’s fair to say that many Gunners supporters weren’t particularly pleased with the Chilean forward.
The incident in question occurred in the 93rd minute of the game, when Christian Fuchs attempted to take a long throw-in.
Sanchez stood in front of the Austrian, twice preventing him from throwing the ball quickly, as the Foxes set about trying to grab a late equaliser.
As a result Fuchs then hit Sanchez, who turned away slightly, on the shoulder with the ball, as it bounced off the pitch once again.
The Chilean, who had started to walk away, then decided to grab his face and slowly fall to the ground.
The reaction was in someway similar to Rivaldo infamously going down and holding his face after it hit his leg in the 2012 World Cup.
Sanchez was booked for his troubles, but Arsene Wenger stood up from him after the game, saying: “I didn’t see where Alexis had been hit.
“In the first two attempts when Fuchs tried to throw ball in Sanchez stood next to him and didn’t know had to be further away.
“Fuchs was lucky not to get a yellow card because he threw ball at him on purpose.”
However, a number of Arsenal supporters didn’t agree with their boss, and took to Twitter to voice their concern.
