The future of Michael Essien at Panathinaikos could not come to an end unless the player himself wishes to leave the club as well.
The Ghanian midfielder has been struggling with injuries since the start of the season. His fitness is getting better, however his debut with the Greens is still on the balance.
Panathinaikos though cannot terminate his contract unless it happens by mutual consent, according to FIFA rules.
Otherwise Panathinaikos will have to wait until the end of the season if Essien fails to appear in less than 10% of Panathinaikos's game in order to see his contract terminated by the club.
