Adana Demirspor players left the pitch in their Turkish Super Lig game at Galatasaray today in protest against a penalty that were awarded to the home team. It was later that the club president issued a statement saying that the players didn't leave the pitch to protest against Galatasaray but against the referee board. The visitors who currently occupy the bottom position in the league went behind when Alvaro Morata scored a penalty in the 12 minute of the game but continued playing until when the club manager signalled to them to leave the pitch.
The ball is now in the court of the Turkish football FA to address the issue and punish any party that deserves to be punished.
I'm not from Turkey and I haven't been able to watch all the Turkish league games, but I find it very strange the large number of penalties that have benefited Galatasaray, I could be wrong, but it's not normal for a team to win so many penalties, I agree that Galatasaray has a very strong squad and they are a very strong team.
