Liverpool winger Sebastian Leto is in hot water at Olympiacos.

Leto is facing disciplinary action after a series of bust-ups with Olympiacos coach Ernesto Valverde.

"During yesterday's training session there was an issue with footballer Sebastian Leto who for the umpteenth time gave in to disciplinary problems forcing me to send him to the dressing room," Valverde said in a statement on the Olympiacos website.

"For this specific incident I have informed the administrative section of the club which is there to deal with it. As I have said in the past, for me the top priority is discipline and the calmness of the team which comes above all of us."
