Chelsea are reportedly sounding out Atletico Madrid boss Diego Simeone and Bayern Munich coach Pep Guardiola as long term replacements for the sacked Jose Mourinho.
Guus Hiddink will take over as interim manager of the Blues for the remainder of the Premier League season, following Mourinho's dismissal on Thursday.
It is understood Simeone is the most likely candidate to take over the full-time role at Stamford Bridge during the summer, although the Daily Mirror is reporting Chelsea are willing to spend big in order to land Guardiola.
The Blues face stiff competition from Manchester City for the services of the former Barcelona manager, whose contract with Bayern Munich expires at the end of the current season.
