Arsenal have suffered a fresh injury blow after rising star Ethan Nwaneri was ruled out for “a few weeks” with a muscular problem.

Nwaneri suffered the injury in Arsenal’s 1-1 draw against Brighton on Saturday and had to be taken off at halftime.

Gunners boss Mikel Arteta confirmed the teenage forward, who had scored his side’s first-half goal against Brighton, faces an extended spell on the sidelines.

The 17-year-old has scored five times in 18 appearances in all competitions this term after emerging from the Arsenal youth academy.
