Jules Kounde did not train with the rest of the Barcelona squad 48 hours before their El Clasico meeting with Real Madrid, according to Diario Sport.
The defender took part in the session but followed an individual programme as he continues his recovery from a sprained ankle ligament.
His absence from full training raises doubts over whether the France international will be included in Barcelona’s squad for Sunday’s match. The club considers it unlikely that Kounde will recover in time, while his chances of starting are even lower.
The La Liga fixture will be played at Camp Nou in Barcelona on Sunday, 25 October. Kick-off is scheduled for 23:00 Moscow time.
