With just a week until the transfer window slams shut, it remains surprising to see Dusko Tosic still a Besiktas player.

The experienced defender was expected to leave the Turkish side this month amid interest from a number of clubs in Britain, and it appeared that the Turkish champions had paved the way for his exit by signing Croatia international Domagoj Vida as a replacement.

But after reported interest from both Celtic and Crystal Palace in the last few days, Turkish outlet Aksam states that a move now looks inevitable before next Wedneday’s deadline.

It is understood that the 32-year-old Besiktas defender, who has won the Super Lig in each of two season with the Turkish giants, has seen his demands of wages increase turned down, and will now step up his attempts to leave Istanbul.

This latest reports should be of interest to a number of interested sides.

This time last week, Gunes stated that the club president Fikret Orman had travelled to London to negotiate a deal with Crystal Palace with Roy Hodgson’s side interested to open talks about signing the 32-year-old Serbian international.

This report came shortly after Celtic reportedly saw a bid of £2.5 million rejected for Tosic, who can play at centre-half or left-back and looks capable of filling holes in The Hoops’ rather thin defence.

It remains to be seen whether the Eagles are still interested, however, after completing the signing of Poland international Jaroslav Jach from Zaglebie Lubin this week.

Turkish outlet Fotomac claimed that both Everton and Leicester City were also interested and, with the pair both seemingly in the market for defensive reinforcements, there should be no shortage of interested side for the defender over the coming week.
