Arsenal boss Mikel Arteta said he had never seen anything like Brighton’s controversial penalty to earn a 1-1 draw on Saturday that dealt another seismic blow to the Gunners’ title challenge. 

Runaway leaders Liverpool hold a five point lead over second-placed Arsenal and have two games in hand. Shorn of many of their most potent attacking weapons, Arteta’s men led at half-time thanks to Ethan Nwaneri’s strike. But two vital points slipped away when William Saliba was harshly punished for a clash of heads with Joao Pedro and the Brazilian slotted home the resulting spot-kick.
