Such success, along with his close relationship with Chelsea owner Roman Abramovich, has led to much speculation that Hiddink might be convinced to extend his stay at the club.
Mourinho - now Inter Milan boss - left Chelsea in September 2007 having led them to back-to-back Premier League titles in 2005 and 2006 and remains a popular figure amongst Chelsea fans.
Another manager who has been heavily linked with the Chelsea job is AC Milan coach Carlo Ancelotti.
The latest speculation suggested he would be offered a deal that would bring him £1m for every trophy he won with the club, but on Saturday he said "I exclude the possibility" when asked about moving to Stamford Bridge.
