This is what it's come to. One of the greatest managers in the world is suffering an unprecedented fall, and by far enduring the worst spell of his career. Jose Mourniho's place as Chelsea manager is becoming increasingly insecure. Who could the possible replacements be ?

Guus Hiddink

An exceptionally clever man-manager and tactician with a supreme record, and well used to being dropped in difficult situations where good teams are going through a bad time. He did it at Chelsea in 2008-09, after all, having won the FA Cup that season and brought them to within a last-minute Andres Iniesta goal of beating Pep Guardiola's Barcelona in the Champions League semifinal.

Diego Simeone

Diego Simeone The Atletico Madrid boss has turned the La Liga outfit into a top European side and a real challenge to the top two in Spain. Passionate, no nonsense and loveable, Simeone could be exactly what Chelsea need to turn their sinking ship around. Good relationships with big name players is what has helped Simeone succeed and the chance to come to England could be hard to turn down for the fiery Argentine.

Carlo Ancelotti

Carlo Ancelotti is one of the most experienced managers currently out of work after being let go by Real Madrid over the summer.The Italian won the Premier League and FA Cup with the Blues in the 2009/10 season and has made clear his intentions to get back into management.

Gianfranco Zola

Pep Guardiola Dragging Guardiola away from Bayern mid-way through a season would be tough for Chelsea, but a summer deal is viable. That would mean giving the job to someone simply until the end of the season, but can Chelsea afford to do that? They need their man now and so Guardiola could be an attractive, yet unrealistic target. The former Barcelona boss has a sensational record as a manager and any team would love to have him.
