He is one of the past decade's most influential football men - and Jose Mourinho's likely exit from Real Madrid could cause shockwaves across Europe.
Let's look at the potential consequences of the Portuguese coach returning to Chelsea, spanning four countries and six elite managers.
Jose Mourinho: Real Madrid to Chelsea
First things first, Mourinho made the strongest indication yet that he is on the verge of rejoining the Blues, following Real's defeat to Borussia Dortmund in the Champions League semi-final. "I know in England I am loved," he told ITV Sport after Tuesday's second-leg encounter, "I know I am loved by some clubs, especially one."
Chelsea's status in European football appears to be the only doubt, with the club having so far failed to secure the top four Premier League position needed to qualify for the Champions League. However, interim manager Rafael Benitez looks certain to leave London in June and his predecessor Mourinho is by far the bookies' favourite to take over.
Carlo Ancelotti: Paris Saint-Germain to Real Madrid
Sources at The Sun recently revealed that Ancelotti, another former Chelsea manager, is ready to replace Mourinho at the Bernabeu and that they are simply waiting for the Special One to confirm his departure in the coming weeks. The Italian is believed to be a long-term target of Real Madrid executives, who twice tried to lure him away from AC Milan.
Arsene Wenger: Arsenal to Paris Saint-Germain
PSG owners are confident that they have persuaded Wenger to join the French side, according to the Daily Telegraph, with Ancelotti preparing to announce his resignation as soon as their Ligue 1 title is secured. Meanwhile, the legendary Arsenal manager will surely be prised from the final year of his contract, after eight years without a trophy.
Joachim Low: Germany to Arsenal
The Sunday Times has reported that Low is prepared to leave his role as German national team manager in favour of the Premier League club, where he would three times his present salary, and that he is the first name on Arsenal executives' shortlist.
Jupp Heynckes: Bayern Munich to Germany
Despite being forced into retirement by Guardiola's appointment at Bayern, the legendary manager could be tempted to manage a talented group of young players within the national setup. The Daily Telegraph reports that he is favourite amongst the German FA.
Pep Guardiola: Unemployed to Bayern Munich (Confirmed)
Alongside the Special One, the former Barcelona boss was revered by all of the above clubs earlier in the season, as well as both Manchester teams. Yet, the Spaniard announced last month that he will join this season's Champions League favourites next year, thus completing the six degrees of separation with his former La Liga rival Mourinho.
