If Guus Hiddink's CV is anything to go by then Chelsea have got themselves one hell of a manager.
CVs can be deceptive though and are by no means a guarantee success will be achieved - just ask Luiz Felipe Scolari.
But it is hard to argue against Hiddink's record that includes the European Cup, the World Club Cup, six league championships and three domestic cup final victories.
Hiddink is highly respected in his native Netherlands, where he helped PSV Eindhoven punch above their weight, while his record in international management is equally impressive.
He took Netherlands to the quarter-finals in Euro 96 and the semi-finals of the 1998 World Cup, though on both occasions the Dutch went out on penalties.

Perhaps even more impressive was his stint as manager of South Korea when the World Cup minnows reached the semi-finals of the 2002 tournament.
Four years later, Hiddink, while coaching PSV at the same time, took Australia to their first World Cup for 32 years, where they reached the last 16, before going out to Italy.
More recently, Russia reached the semi-finals of Euro 2008 under Hiddink's guidance.

Importantly for Chelsea, Hiddink already enjoys a close relationship with owner Roman Abramovich, who has been paying his salary as Russia coach.
Abramovich tried to tempt Hiddink to Stamford Bridge once before, in 2007, when Jose Mourinho left the club. Then Hiddink said no, but Abramovich finally has his man.
"Abramovich does so much for Russian football that I wanted to do something back," said Hiddink.
One of Hiddink's strengths is his willingness to make bold tactical changes as England found to their cost in a Euro 2008 qualifier when the Dutchman's introduction of Dmitry Torbinsky and Roman Pavlyuchenko changed the game, with the latter going on to score twice in Russia's 2-1 win over Steve McClaren's side.
"The most important thing is, he never panics," said PSV football manager Stan Valckx.
But it is his man-management skills that are most likely to be in demand when Hiddink finally arrives at Stamford Bridge with captain John Terry hinting that some players had not been fully supportive of Scolari.
Throughout the Dutchman's managerial career he has had to deal with plenty of big egos - just ask Edgar Davids, who was ejected from the Netherlands' Euro 96 squad, with Hiddink believing team unity was being fatally disrupted.
