The Dutch coach is not sure if the centre-back can feature in the Champions League in midweek but does not expect him to be absent for long
Ronald Koeman is hopeful that Clement Lenglet's injury is not serious after the defender was forced off during the 4-0 win against Osasuna on Sunday.
Lenglet had to be replaced midway through the second half when he sustained an ankle injury following an aerial challenge with Osasuna's Ruben Garcia.
Barca were already short in defensive options, with centre-backs Gerard Pique, Samuel Umtiti and Ronald Araujo ruled out with injuries, leaving Koeman with no option but to bring on Carles Alena to replace Lenglet.
