Two former Tottenham players were involved in a huge brawl during the middle of Besiktas' 3-2 victory over Ankaragucu.
The incident started when both sets of players started to argue in the centre of the pitch, before Besiktas midfielder Salih Ucan was attacked by a violent fan who dropkicked the player.
The referee had been trying to calm the match down as the fan approached the group of players in the centre circle. He also made contact with former Everton striker Cenk Tosun, before Josef de Souza - who would go on to be sent off - managed to restrain the fan and force him to the floor.
