Roberto Di Matteo surprisingly became the first Premier League manager to lose his job. QPR boss Mark Hughes is currently the odds-on favourite to become the next inline, followed by Roberto Mancini.
Di Matteo was sacked by Chelsea on Wednesday morning after a 3-0 Champions League defeat to Juventus left them in danger of becoming the first holders to exit the competition in the group stage.
The Italian manager also oversaw a winless run of four games in the Premier League and two defeats in the last three European ties, but Gullit, who managed Di Matteo during his time as Chelsea manager, remains shocked at the timing of his departure.
"I can't believe that Chelsea just sacked him without knowing who is going to be the next one,'' Gullit told Sky Sports News.
"I will be curious to see what they do in the next couple of days. I can't believe they have just sacked him out of the blue and then they'll be thinking about who is going to be the next one. I don't think so.
"I think they have already in mind who is going to be the next one. It could of course be Mourinho, if it happens, I don't know because it is in the middle of the season.
"I already had a very good feeling that when Robbie won the Champions League that maybe they (the Chelsea board) already had somebody else in the frame to take over," he said.
"I don't think they took any notice of the fact that Robbie could win it. That was the reason I believe that they took so long to sign Robbie because they were looking for other people. In the end they gave it to Robbie.
"I always had the feeling that Mourinho was in the frame all the time - for the simple reason that he signed just after Chelsea won the Champions League. He signed his contract with Real Madrid and for me that is no coincidence."
Manchester United defender Rio Ferdinand echoed Gullit's disbelief, describing Di Matteo's sacking as "madness" and advocating the need for managerial stability in order to bring sustained success.
