Turkish football has become embroiled in more controversy over the treatment of referees after a top-flight game was abandoned due to one team walking off the pitch in protest at a decision. Istanbulspor president Ecmel Faik Sarıalioglu told his players to leave the field midway through the second half of Tuesday’s Super Lig game against Trabzonspor. The controversy was sparked when Trabzonspor went 2-1 ahead with a goal from Paul Onuachu, after Istanbulspor players had earlier claimed they should have had a penalty following a clash between Florian Loshaj and Batista Mendy.
