Chelsea's decision to part company with Andre Villas-Boas has created yet another managerial vacancy at the perennially unfulfilled club.
A genuine vacancy, unlike the assumed one at Tottenham Hotspur, that may be forthcoming anytime between now and August should Harry Redknapp take the England job as expected.
Villas-Boas' sacking has implications for them in that their London rivals now will also be looking at candidates Spurs may have been eyeing up in case of a possible Redknapp departure.
Both jobs differ in expectation and the materials available to work with for each's respective incumbent, but both can claim to offer candidates the chance to work with a top-six club.
Just who Spurs might be looking for remains to be seen.
Redknapp's appointment in October 2008 was a break away from the continental system Daniel Levy had previously structured his club with since 2004. Critics of this system, which utilises a controversial sporting director role to oversee player recruitment, often negate to examine the reason why the Tottenham chairman implemented it in the first place.
Levy was keen to move on from a series of managerial hirings that had failed to turn Spurs into a club capable of challenging for a regular top-six position. While it worked for a time in realising a different approach of bringing players to the club, it was not entirely different from before in that its success was essentially down to the personality of the manager.
Jacques Santini and Juande Ramos were both managers appointed on the basis of their records, but both failed to adjust to English football in the way Martin Jol did. The Dutchman blended an amiability with media and supporters with an understanding of his players that for two and a half years proved fruitful.
Though Levy did not believe Jol capable of taking the club further than his two fifth place finishes, his eventual appointment of Redknapp indicated a realisation of certain fundamentals needed by a manager to excel in the Premier League.
Replacing Redknapp will not be easy either this summer or down the line. But knowing what we know about the type of manager that has done well at Tottenham in recent times, here are five managers they might well be having to look to bring in this summer.
