Real Madrid coach Manuel Pellegrini has fallen out with Lassana Diarra.
The former Portsmouth and Chelsea midfielder is unhappy with his treatment in recent games and Marca says the pair were seen arguing at training this week.
Pellegrini is expected to dump Diarra for Fernando Gago for their next clash with Getafe.
Asked about the row, Pellegrini waved away the questions: "If a player doesn't make the pitch, it's not because they've done wrong."
