The trial of Greece's Olympiacos football club chairman Evangelos Marinakis and dozens of soccer fans began in Greece on Wednesday, the biggest case of its kind linked to sports-related violence that authorities have vowed to crack down on.

Nottingham Forest manager Nuno Espirito Santo said "football is emotions" after club owner Evangelos Marinakis confronted him on the pitch following a 2-2 draw at home to Leicester on Sunday that threatens to scupper their hopes of Champions League qualification.

Nottingham Forest owner Evangelos Marinakis will not have a controlling interest in the Premier League club next season, making the move ahead of their potential return to European football.
