Roman Abramovich is reportedly considering Guus Hiddink as a potential replacement for Andre Villas-Boas as tension between the Chelsea manager and his players rises.
Villas-Boas is reported to have been at loggerheads with some of his senior players following the weekend defeat to Everton, and angry words have been exchanged.
The Portuguese cancelled a day off for the players on Sunday, calling them in for an extra training session after the 2-0 loss at Goodison Park.
This had lead to suggestions that Villas-Boas' days at Stamford Bridge could be numbered, and Hiddink is being touted as a possible successor to the 34-year-old.
According to the Daily Mail, Chelsea owner Abramovich is already looking at alternatives to Villas-Boas, and is aware of Hiddink's availability.
The veteran Dutch manager is currently out of work after leaving his post as Turkey's national boss, and is known to maintain a good relationship with Abramovich.
Hiddink led Chelsea to a triumph in the final of the FA Cup in 2009, having taken over as caretaker manage following the dismissal of Luiz Felipe Scolari.
