Arsenal news: Granit Xhaka is missing for Arsenal's clash against Southampton at the Emirates Stadium
The current gap sits at four points to second-placed Manchester City, however they have played a game extra over their rivals. That will become two after the match, with the Cityzens in cup action this weekend, though it could become an opportunity to get valuable points on the board before a head-to-head next week.
The absence of Xhaka may be felt though, given his resurgence into form over the season with his move into a move advanced role on the left. The midfielder is out of the squad due to illness and there will be concern over whether he will be available for the clash with Man City next week.
It remains to be seen if the youngster will be involved, but it would be a double blow for the Gunners if he were to miss the tie while doubts hang over the return of Xhaka before next week.
