Tottenham boss Mauricio Pochettino says he is not involved in defender Toby Alderweireld's contract negotiations that have reportedly stalled.

Belgium's Alderweireld, 28, could be sold by Spurs after a deadlock in talks, according to reports.

The former Ajax player's current deal expires in the summer of 2019.

"It is not my job and I cannot say anything about that," Pochettino said when asked about Alderweireld's future on Friday.

"I am not involved in negotiations. I never talk about rumours, what the media say or what happens around the club."
