However, after Brentford showed an interest in his signature, he has opted to make the move to England for an undisclosed fee.
Brentford boss Dean Smith told the club's official website: "I am pleased that we have been able to add Kamo to our group now he has become available. He is a player that we have been looking at for a while and we are sure he will fit into the system and style that we have here.
"Kamo is a defensive midfielder who can break play up, cover a lot of ground and use the ball intelligently. He is a player that will certainly add to the qualities we already have within the squad."
Mokotjo - who has represented South Africa on the international stage - has penned a three-year contract at Griffin Park.
