Guus Hiddink is moving closer to a return as Chelsea manager after admitting he would consider any offer to go back to Stamford Bridge.
Hiddink is guiding Turkey through a Euro 2012 qualification campaign but has not dismissed out of hand a return to the role he filled on an interim basis after Luiz Felipe Scolari was dismissed early in 2009.
Hiddink, at a Turkey training camp, said of speculation linking him with Chelsea: "If there was a concrete offer, then I would think about it."
However, Hiddink would not commit to a possible return to take over from Carlo Ancelotti, adding: "There's nothing concrete. You cannot go into all kind of speculation or rumours because there's nothing concrete. The moment things are concrete, I'll go to where I have to be, direct.
The 64-year-old Dutchman has already talked about his appetite for club football and a return to the Barclays Premier League club to work for owner Roman Abramovich would appeal having previously worked for him at Chelsea and indirectly for the Russian national team.
Abramovich supported Hiddink's dual role with both Chelsea and Russia through his financial support of the Russian team.
At the moment though, Hiddink is unlikely to break his contract with Turkey, who face a crucial qualifier with Belgium in Brussels on Friday, with the nation in contention to finish second in Group A and secure a November play-off ahead of the finals in Poland and Ukraine.
He said: "First, get this game done next Friday, a difficult game, you know. Then we'll see."
