Mathieu misses final training session before the Clasico
The Frenchman is a doubt for Sunday's game against Madrid
Kaptoum, Aleñá and Carbonell took part in Saturday's session
Barcelona trained on Saturday ahead of Sunday's important league game against Real Madrid, a match which must be won if Luis Enrique's side want to win La Liga.
Jeremy Mathieu, due to a problem with his Achilles tendon, did not train with his team-mates and is expected to miss the game at the Santiago Bernabeu.
Elsewhere, Arda Turan did train without problems once again and should receive the green light to travel to Madrid.
Also present in Saturday's session were Aleñá, Carbonell and Kaptoum. The first of those three could be in the squad again, as has been common in recent weeks.
Remember that the only players out with long-term injuries at the moment are Aleix Vidal and Rafinha.
