Middlesbrough boss Gareth Southgate hopes to be able to tie Abel Xavier to an extended Riverside Stadium stay at the end of this season.
The Portuguese defender had previously said that he could leave the club in this month's transfer window, but it is the first Southgate has heard of it.
"There's no clause in his contract, he's our player until the end of this season and then we'll be looking to sit down and try to extend that," Southgate told Boro's official website.
The 34-year-old returned to the club in November 2006 after serving a one-year drugs ban.
He has been part of Southgate's first-team plans ever since, making six appearances for Boro, including a starting place in Saturday's FA Cup third round clash at Hull City.
