Arsenal welcomed Manchester City to the Emirates on Saturday in what turned into one of the games of the season with controversy aplenty in north London.

Bukayo Saka fired an impressive Arsenal into the lead in the first half, finishing coolly from a Kieran Tierney pass to give Mikel Arteta's men a deserved 1-0 advantage.

But a shirt-pull from Granit Xhaka on Bernardo Silva gave City the perfect opportunity to draw level from the penalty spot, Riyad Mahrez making no mistake after a VAR check.

Just moments later, Gabriel Magalhaes received a second yellow card for a lazy body-check on Gabriel Jesus, further infuriating the home crowd.

Rodri sent the away fans into bedlam in injury time when he poked home the winner, leaving too Arsenal fans and players deflated at full time.

In an action-packed match, Arsenal striker Gabriel Martinelli still managed to find his way into the heart of the action again, although not by finding the back of the net.

While the Gunners still held a slim advantage, the Brazilian was on the receiving end of a clattering challenge from Rodri, leaving him in pain on the north London turf.

But some eagle-eyed supporters watching back home noticed referee Stuart Attwell appeared to kick the head of Martinelli while he writhed in agony.

@BamBamMickey said: "The referee kicked Martinelli in the head lol."

@ZanyFi said: "Anybody else see the referee's shin on Martinelli's face?"

@AFC_Aubamelli said: "Ref kicked Martinelli in the head, send him off. Needs to give himself a red."

The incident was of course completely accidental and did not appear to harm Martinelli in the slightest but added yet another bizarre moment to a dramatic game.
