Sven-Goran Eriksson and Ole Gunnar Solskjaer are the early favourites to replace Malky Mackay at Cardiff.
It remains to be seen who will be willing to work under owner Vincent Tan but here, Press Association Sport looks at some who may be in the running.
It is assumed Sven has the sort of worldwide gravitas Tan is looking for and, having travelled the globe in pursuit of work, may have no qualms in throwing his lot in with Cardiff. Currently with Guangzhou R&F but could he resist another shot at English football?
The lifelong fan has ended his playing career with the club and played a key role as they eventually made it to the Premier League. Nothing suggests he would want the job but, if he is keen on a career in coaching, perhaps this could be his chance.
Turk Vural has managed more than 20 clubs in his homeland and was recently linked with a move to Cardiff. The club denied being in contact with the 60-year-old but his name refuses to go away.
Initially sacked by Tan in 2011 after consistently failing to deliver promotion, he is now out of work after losing his job at Sheffield Wednesday. It would take a significant thawing of relations for him to get the position, but he is certainly available and has been linked.
OLE GUNNAR SOLSKJAER
Another product of Sir Alex Ferguson's managerial academy, Solksjaer has earned a fine reputation with Molde in his home country of Norway, winning the league twice and the cup once. Would certainly be attracted by the Premier League but it remains to be seen if mentor Ferguson would advise him to stay away.
