Real Madrid pair Sergio Ramos and Iker Casillas reportedly requested a 25-minute team meeting before the club's training session on Monday.
The Spanish outfit have lost just once this season – Saturday's 1-0 loss to Atletico Madrid – but it is understood that friction in the camp has led to internal issues.
According to COPE, Ramos and Casillas insisted to boss Carlo Ancelotti that a meeting should be held to discuss potential problems in the camp and the team's form in the early part of the season.
The performances of Karim Benzema this season have also reportedly drawn criticism from inside the club ahead of Wednesday's Champions League clash with Copenhagen.
