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.
The 64-year-old Dutchman has already talked about his appetite for club football and a return to the 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.
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.''
But 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.
However, Hiddink would not commit to a possible return to take over from Carlo Ancelotti.
He added: ''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. First, get this game done next Friday, a difficult game, you know. Then we'll see.''
Former Chelsea striker Jimmy-Floyd Hasselbaink believes Hiddink would be the obvious replacement for Ancelotti at Stamford Bridge.
''I know him very well,'' he said. ''He was the one that gave me my first cap for Holland. He is a very intelligent football man and a very good football man.
''He has already been here at Chelsea and was a success, so I can understand him being the favourite.Guus has already proved himself, he has already been here. That would be an easy one I think.''
While speculation over who should take the helm at Chelsea is rife, another of the club's former players says he has little sympathy for the outgoing Ancelotti. Marcel Desailly made 156 appearances for the Blues up until 2004 and admitted he understood the thinking behind the Italian's removal.
''That is the life of a manager,'' said the former France centre-back. ''He did well in the first year and won two trophies, but the owner did not support the fact that this year he won nothing. The message to the players was still positive but the management have clearly decided that was not enough.
''I love (bookmakers favourite) Harry Redknapp, but it doesn't matter who they pick. I just want them to decide very quickly. That way we can get on with planning and dreaming of victory.''
