Arsenal closed to within four points of Premier League leaders Liverpool as substitute Mikel Merino's two late goals gave them victory at struggling Leicester City.

The Gunners' striker shortage threatened to be exposed by the Foxes until Merino, on for the desperately out-of-sorts Raheem Sterling, stole in at the far post to break the deadlock.

Merino's 81st-minute goal was created by Arsenal's outstanding player, 17-year-old Ethan Nwaneri, who hit the woodwork twice in the second half and was their main threat throughout.

Spanish midfielder Merino then struck again at the far post three minutes from time to wrap up a vital win and keep Arsenal's title pursuit on track.

It was tough on Leicester, who fought hard throughout and almost took the lead, only for Myles Lewis-Skelly to get a vital touch with Bobby de Cordova-Reid waiting to tap in Jordan Ayew's cross.

Arsenal's celebrations carried an element of relief as for a long time it looked like their lack of strikers, made worse by Kai Havert's hamstring injury sustained on their break in Dubai, was threatening to undermine them - until Merino stepped up.
