Arsenal manager Unai Emery may not risk playing the returning Laurent Koscielny in Sunday’s Premier League match against Southampton

The French defender made his return for Arsenal in their 1-0 Europa League win over Qarabag FK on Thursday night after a seven-month absence due to Achilles tendon injury.

Koscielny managed 72 minutes of action at the Emirates Stadium before being replaced by Nacho Monreal.

Despite a lack of defensive options at his disposal right now, however, Emery suggested that he will not force Koscielny to play at Southampton this weekend.

“We are doing with him this process after the big injuries,” said Emery on Arsenal.com.

“He started training with us, playing with the under-23s, and today was another step for him, for us and we need to know tomorrow and Saturday how he is going to feel after this match. If Sunday we can [play] him on the pitch.

“When a player comes back like Koscielny, after a big injury… a very big injury, it can give the player different moments.
