According to reports in France, Tottenham defender Younes Kaboul is a target for Besiktas.
There haven't been many, but one of Mauricio Pochettino's biggest mistakes at Tottenham so far may well be handing the captaincy to Younes Kaboul last summer.
Pochettino arrived from Southampton and sold Spurs captain Michael Dawson, meaning he had to appoint a new skipper so soon into his reign.
Hugo Lloris and Jan Vertonghen were touted as the frontrunners, yet Pochettino bizarrely gave Kaboul the armband, despite Spurs fans considering the Frenchman to be little more than an afterthought in defence.
Kaboul started the season fairly well, especially with a colossal display against Arsenal in the North London derby, but has since reverted to type, being ponderous and error-prone in defence.
His last appearance for Tottenham came away at Besiktas in the Europa League a month ago, and it's the Turkish side who are reportedly interested in signing the 29-year-old.
France Football claim that Kaboul has been approached by Besiktas ahead of a possible transfer this month, with the former Portsmouth defender relegated to fourth choice behind Federico Fazio, Jan Vertonghen and Vlad Chiriches.
Given the lack of playing time he has received lately, it would be little surprise to see Pochettino sanction an exit for Kaboul during the transfer window.
Pochettino hasn't made many big errors so far during his reign at White Hart Lane, but giving the captaincy to Kaboul is one - and now he may have the chance to rectify his error by letting him leave.
