Southampton have received a welcome boost ahead of their trip to London as Arsenal defender Laurent Koscielny is doubtful to feature, according to a report on the Daily Echo.

The French centre-back limped off during Arsenal’s Europa League round of 32 second leg victory over BATE Borisov at the Emirates Stadium.

The defender picked up a calf problem and is currently being assessed by Arsenal’s medical staff ahead of Sunday’s match.

Koscielny is a danger at set pieces and has proved his worth to the Gunners with some important goals in recent months. 

Ralph Hasenhuttl’s side will be hoping to frustrate the Gunners and hit them on the counter.

The Saints have been boosted by the return of Michael Obafemi and Stuart Armstrong, who are both back in full training and in contention to play at the Emirates. 

Do you think Southampton will win against Arsenal on Sunday?
