Chelsea are thought to be planning talks with Jose Mourinho and Pep Guardiola over the vacant manager's job at Stamford Bridge.
Andre Villas-Boas was sacked on Sunday after just nine months in charge at the club.
Former boss Mourinho has been heavily linked with a return to the Blues following rumours that he could walk out on current club Real Madrid in the summer.
Barcelona manager Pep Guardiola's future at the Nou Camp is similarly unclear while he stalls over a new deal with the European champions.
Both men are expected to be approached by Chelsea owner Roman Abramovich over the summer, according to The Guardian.
Villas-Boas' assistant Roberto Di Matteo has been put in charge of the side on an interim basis until the end of the season.
