Turkish Super Lig champions Galatasaray want to sign Torino's Kamil Glik, according to Italian website Tuttomercatoweb.
Polish international centre-back Glik was named as a transfer target for English Premier League side Tottenham Hotspur by The Sun just two months ago.
The Mail today reported Kaboul is also being considered by Premier League new boys Watford.
Glik began his career with Real Madrid, and was Torino's second top scorer last season behind Fabio Quagliarella despite being a centre-back.
Time is running out, and Tottenham's other options
If Galatasaray - and indeed Tottenham - are serious about Glik they will need to act quickly.
Torino president Urban Cairo was quoted by Tuttomercatoweb a month ago saying the club will not sell any players after June 30, having felt to have got a raw deal by caving in on deadline day last summer to sell Alessio Cerci to Atletico Madrid.
Should the Turkish side be unwilling or unable to meet the deadline it could accelerate their interest in Younes Kaboul.
Spurs themselves have already signed one centre-back this summer in Kevin Wimmer, and the London Evening Standard reported this week that last season's Southampton loanee from Atletico Madrid, Toby Alderweireld is keen on a move.
