Having led the table for much of last season before being pipped at the post by Manchester City, Arsenal are back in pole position to end their title drought this term.
Mikel Arteta's men are two points clear at the top of the standings, and have lost just once in the league all season.
But concerns have been raised about the Gunners' front line. Arsenal have netted just 29 goals in their 14 games, putting them sixth in this category behind the likes of Newcastle (32) and Brighton (30), who are both outside the Champions League places.
