Guti's future at Real Madrid remains in doubt. Real coach Juande Ramos insisted he left the midfielder out of Sunday's victory over Almeria only because he couldn't fit him into his in-form starting XI.
However, Sport says the pair rowed in Friday's training session, which led to him being dropped for the game.
Guti is contracted to Real until 2011 and may consider his options should Ramos remain in charge next season.
Interestingly, his one start in recent times was against Atletico Madrid - which led to the end of Real's winning streak.
