Starsport revealed last week that behind the scenes he is making no secret of his desire to quit the Emirates at the end of the season.
While Wenger said the decision was based on tactical reasons, newspaper reports Sunday evening said it was because the Arsenal boss had lost patience with the star striker's attitude in recent weeks.
Instead of playing a more direct style, Arsenal continued to play like they have all season, with intricate passing along the ground.
There has been some talk that Sanchez is reluctant to renew his contract with Arsenal, which expires in the summer of 2018, but if Wenger left Sanchez on the bench as a form of punishment, it cost the club a much-needed three points.

Georginio Wijnaldum finished the Gunners off with a goal in stoppage time. That can be attributed to two factors: poor defending from the midfield back, and the inexplicable decision to rest Alexis Sanchez until the second half.
Arsenal had some more opportunities, but Liverpool was clearly the better side with the better plan. Man City was: "We can do it sometimes"; Sunderland was: 'Yeah, that is the usual face.' So we have to keep on going in these parts and then, finally, probably everything will be good.
