Galatasaray coach Fatih Terim is facing the threat of a 10-match suspension for criticising the referee during his side's league match against Mersin, Turkish media said on Monday.
Terim, who leads the Istanbul club in their return leg Champions League quarter-final match against Real Madrid on Tuesday, was banished to the stands with a number of his coaching staff during Saturday's game, which Galatasaray won 3-1.
The manager, visibly angry, at one point went on to the pitch, grabbed the matchball and violently threw it to show his anger about a string of decisions.
Newspapers Hurriyet and Vatan, quoting the official match report, said Terim insulted the referee and a Turkish football federation (TFF) representative.
The TFF was expected to make a decision on the incident in the coming days and could impose a severe sanction, according to the press.
