Just after the break, Xhaka was involved in one of the game's major talking points.
He horrifically lunged into a tackle with Raphinha, catching him directly on the ankle that sent the Brazilian winger to the floor in agony.
Match referee Andre Marriner, though, did NOT brandish any card for the Swiss midfielder to the anger of fans and critics online.
No booking :eyes::x:
Granit Xhaka has got away with one there!

Gary Neville, who was on commentary duty, took exception to the player's reaction as he smiled while Raphinha was stricken on the ground.
Then, moments later, Joe Gelhardt picked up a caution for a similarly reckless tackle on Takehiro Tomiyasu.
Needless to say, Marriner failing to send off Xhaka sent social media wild.
Granit Xhaka should be off. Shocking challenge on Raphinha.

Gelhardt with a near identical challenge on Tomiyasu. Yellow card. Was no booking for Xhaka. Not gone down well. #lufc

One tweeted: "And the ref proceeds to book a Leeds player for a tackle like that one 2 minutes later."
A second took aim at VAR: "VAR at its corrupt best again... top clubs get away with so much How the hell has he not been booked for that tackle after getting checked..."
A third added: "Worst group of referees for a long time, neutral fan on this game and that's a stonewall red."
As for the actual match, Marcelo Bielsa's team suffered a crushing 4-1 home defeat to Arsenal.
It comes after his side were smashed by Manchester City 7-0 in midweek.
