Beşiktaş are preparing to offer Czech Republic international Tomas Sivok a new deal according to the Milliyet.
Sivok has spent the last seven seasons at Beşiktaş and has recently reestablished himself as a first team regular.
The experienced defender was expected to leave at the end of the season following the arrivals of Pedro Franco and Alexander Milosevic however, the Czech international has been able to remain an important member in the squad.
Beşiktaş manager Slaven Bilic is reported to be keen on Sivok staying. The 31-year-old is one of the most experienced players in the team.
The Black Eagles will be able to sign 14 and play 11 foreign players at any one time following the rule changes implemented by the Turkish Football Federation (TFF) that come into effect next season.
The 31-year-old joined Beşiktaş from Udinese in July 2008 for €5 million.
The defender has made 14 appearances for the Black Eagles this season.
Sivok has 48 international caps for the Czech Republic.
