Midfielder Cesc Fabregas will not feature against his former club due to a minor injury, but Sarri hopes he will be back in training next week despite describing it as “a very unusual injury”.
“He has a pain, not in the knee, [but] near the knee,” said Sarri.
Arsenal will be without Ainsley Maitland-Niles after he suffered a small fracture to his leg in last weekend’s defeat to Manchester City that could rule him out for up to two months.
Maitland-Niles played at left-back in that loss and is likely to be replaced by fit-again Nacho Monreal, with Danny Welbeck also back in training, but Sead Kolasinac (knee), Laurent Koscielny (Achilles) and Carl Jenkinson (ankle) are absent.
