After their 2-2 draw at Manchester United, Emery says the defender is fully recovered from Achilles surgery.
He said, "Laurent is very close to playing for us.
"He played two matches for the under-23s - the last one was on Tuesday. When are we thinking he will start playing with us? I don't know if Saturday is a possibility, but we're thinking the Europa League game against Qarabag could be a good match for him."
