Arsenal ignored their injury woes to close the gap on Premier League leaders Liverpool as Mikel Merino inspired a 2-0 win against Leicester, while Omar Marmoush's hat-trick fired Manchester City's 4-0 rout of top four rivals Newcastle on Saturday. Mikel Arteta's side were in danger of wasting a chance to put pressure on Liverpool in the title race as they laboured to make the breakthrough at the King Power Stadium. With his attacking options limited by a host of injuries, Arteta sent on Spain midfielder Merino to act as a makeshift striker in the closing stages.
