Chelsea are considering a fresh move for Borussia Dortmund coach Jurgen Klopp as they continue their search for a new manager. Everton boss David Moyes and Malaga's Manuel Pellegrini are the two other strongest possibilities.
Former Chelsea manager Jose Mourinho is pushing to be considered but, while the Real Madrid coach has his supporters within the Stamford Bridge hierarchy, there are serious concerns about him returning.
Klopp rebuffed Chelsea's tentative interest last season, signing a new contract at Dortmund to 2016, and it remains unlikely that he would want to move, with an expectation that he is keen to eventually succeed Joachim Loew as coach of the German national team. However, Chelsea are taking soundings about the 45-year-old's suitability.
Chelsea are also continuing to monitor developments at Everton, with Moyes' contract coming to an end this summer.
The expectation is that Mourinho will leave Real at the end of this season and there is a growing sense that he is lobbying to become the next coach of Paris Saint-Germain should Carlo Ancelotti be removed from his post. At the same time Mourinho's associates have let it be known he would be interested in a return to Chelsea, where was sacked in 2007 after falling out with Abramovich.
Meanwhile, Nottingham Forest are searching for their fourth manager in nearly seven months following the resignation of Alex McLeish only 40 days after his appointment. Former manager Billy Davies is emerging as a possible contender to replace him.
