Roman Abramovich is reported to be actively considering potential replacements for Andre Villas-Boas following Chelsea's defeat against Napoli on Tuesday night, and Rafael Benitez has emerged as frontrunner for the position.
The Blues had taken the lead through Juan Mata at the Stadio San Paolo, but saw their hopes of Champions League progression severely dented by goals from Ezequiel Lavezzi and Edinson Cavani.
According to The Telegraph, Benitez is the young Portuguese's most likely successor, and could be shipped into Stamford Bridge for the remainder of the season.
In the wake of Chelsea's defeat, a club source reportedly suggested that it is '75 percent certain' that Benitez would take over, should Villas-Boas be relieved of his duties.
Benitez has been out of work since leaving Inter Milan in December 2010, but can boast a CV including three league titles and a Champions League triumph.
