Mikel Arteta proved himself a master of improvisation as he made light of his striker shortage by turning a midfielder into his match-winner and keeping Arsenal in the title race.
With Kai Havertz sidelined for the rest of the season and Bukayo Saka, Gabriel Martinelli and Gabriel Jesus also missing through injury, Arteta rolled the dice midway through the second half. With his team struggling to break down Leicester, the Gunners boss brought off Raheem Sterling and sent on Mikel Merino. The summer signing from Athletic Bilbao responded with two goals to sink Leicester.
