Emery will take no risks with returning Koscielny after seven months out.
Arsenal manager Unai Emery has confirmed Laurent Koscielny could make his first Arsenal appearance since May.
The Gunners skipper has been sidelined since rupturing his Achilles in the Europa League semi-final second leg against Atletico Madrid in May, but could be in the squad on Saturday when they face Huddersfield.
“We are on the right way with him. They played two matches with the Under-23s. The last was 80 minutes on Tuesday," said Emery.
“Our plan is maybe come here with us in the 18 for Saturday, and one plan is maybe he can play against Qarabag in the Europa League.
“He is working with us with very big performances in training, and is playing in the U23s with good feeling – the next step is to play with us.
“[He brings] experience, quality, personality. We need every player. The next step is playing.”
