Guus Hiddink is ready to return to Chelsea.
The Daily Mail says Roman Abramovich is already considering alternatives to Andre Villas-Boas and is well aware of Hiddink's availability.
Hiddink, who is out of work and was playing golf in his native Holland yesterday, refused to discuss a potential return to Chelsea.
The Dutchman was parachuted into Stamford Bridge to replace Luiz Felipe Scolari in 2008 and ended the season by winning the FA Cup in 2009.
Hiddink has made it his policy not to talk about managerial vacancies while a club has a manager, but he remains Chelsea's fall-back option.
