Guus Hiddink appears destined to leave Turkey in the middle of their Euro 2012 qualifying campaign, having been in charge for less than a year.
The BBC has reported that a senior source at the Turkish Football Association has admitted they are resigned to losing the 64-year-old Dutchman.
Hiddink could now open talks at English Premier League club Chelsea, with a view to him replacing Carlo Ancelotti.
Hiddink had a temporary spell in charge at Stamford Bridge in 2009 after they sacked Luis Felipe Scolari, and he led them to FA Cup glory that season.
However his commitment to coaching the Russian national team meant his tenure was only temporary.
Hiddink is known to have a strong relationship with Chelsea owner Roman Abramovich.
He has just over a year left on his contract with Turkey, so Chelsea will have to pay compensation if they are to secure him as their new manager.
