Fans were left stunned after Riccardo Calafiori avoided a red card during the 4-2 win for Arsenal over Leicester.
The Foxes staged a remarkable comeback from 2-0 down in a thrilling second half at the Emirates Stadium.
Gabriel Martinelli opened the scoring for Arsenal in the first half and later assisted Jurrien Timber for his first goal with the Gunners before halftime.
However, any hopes Arsenal had of overtaking Manchester City at the top of the Premier League evaporated after the break.
Facundo Buonanotte, on loan from Brighton, pulled one back for Steve Cooperโs team, and then full-back James Justin leveled the score with a stunning half-volley using the outside of his foot.
Arsenal pressed forward in search of a winner and dramatically found it in the fourth minute of seven added minutes through Leandro Trossard, although it was later ruled an own goal by Wilfried Ndidi.
Kai Havertz then sealed the victory for the Gunners with a goal in the 99th minute.
However, fans felt that Arsenal should have been playing against 10 men after a late tackle from Calafiori, who had already been booked.
Leicester City requested a second yellow for Calafiori, but instead, Buonanotte received a yellow card for ap
pealing for it.
