Leicester, United Kingdom (AFP)–Arsenal ignored their injury woes to close the gap on Premier League leaders Liverpool to four points as Mikel Merino came off the bench to clinch a 2-0 win against Leicester 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.

But, 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.

It proved an inspired move as Merino netted twice in the last nine minutes to extend Arsenal’s unbeaten run in the league to 15 games.

Having lost 2-0 at Newcastle in the League Cup semi-final second leg before an extended break due to their early FA Cup exit, the Gunners returned to action with a vital victory that keeps them hot on the heels of Liverpool.

Liverpool, who stumbled with a draw at Everton in their game in hand on Wednesday, can increase their lead back to seven points if they beat lowly Wolves at Anfield on Sunday.

With Kai Havertz ruled out for the season after suffering a hamstring injury while blocking a shot during Arsenal’s recent training trip to Dubai, Arteta was left with a threadbare attack.

Havertz’s injury blow came just weeks after Arsenal failed to sign Aston Villa striker Ollie Watkins during the January transfer window.

Gabriel Jesus, Bukayo Saka and Gabriel Martinelli were already sidelined, so Arteta was forced to use Belgian winger Leandro Trossard as his central striker.

Underling the paucity of Arteta’s forward options, 17-year-old Ethan Nwaneri and the out of form Raheem Sterling filled in on the flanks either side of Trossard.
