Get your 14 day free trial >Allegri will part ways with JuventusSource: AFPWith the hot seat of one of the continent’s top clubs now vacant, and another highly rated coach free to find a new job, a merry-go-round isn’t beyond the realms of possibility.In fact, this call comes at a particularly interesting time, considering the candidates worthy of taking over.Jose Mourinho is without a job. So too are Arsene Wenger and Antonio Conte.Meanwhile, Tottenham boss Mauricio Pochettino has repeatedly threatened to quit the club should they beat Liverpool to lift the Champions League trophy on June 2 AEST. Until now, it loomed as an empty threat.For months Pochettino was touted as the man to take over at either Real Madrid or Manchester United, then within the space of 18 days both roles were filled, and it seemed the Argentine had little choice but to sit tight.But now, he’s been installed as the second favourite to succeed Allegri at Juventus and has a logical exit route should he actually make good on his promise.Jose Mourinho remains without a job…Source: AFPThe only man bookies rate a better chance of landing the gig is former bianconeri boss Antonio Conte. Without work since leaving Chelsea at the end of last season, Conte managed Juve between 2011 and 2014 rather successfully, reeling in back-to-back-to-back Serie A titles.Speaking of the Blues, another name being heavily linked to the role is current Stamford Bridge head coach Maurizio Sarri. According to Sky Sport Italia and Tuttomercatoweb, Sarri is already in talks to join the Italian champions.But one man who apparently won’t be heading to the Allianz Stadium is Pep Guardiola, who was quick to distance himself at his pre-FA Cup Final press conference overnight.“How many times do I have to say? I’m not going to go to Juventus, I’m not going to move to Italy,” Guardiola said.“I’m satisfied here, I’m not going anywhere. Next season I will be manager of Man City, I said many times.”Could Mauricio Pochettino make good on his exit threats and land at Juventus?Source: Getty ImagesSo it appears we can shut that door, but should Juve opt to pursue a different Premier League poach via either Chelsea or Spurs, it would likely spark wider effects around the footballing world.If either of those clubs were to lose their manager, a replacement would likely come from the upper tier of candidates. Thus sparking a merry-go-round of sorts.One thing to note though, is the reasoning behind Allegri’s split with Juve after sealing yet another domestic title.READ MORE:RUMOUR MILL: SHOCK ESCAPE ROUTE FOR ALEXIS SANCHEZFA CUP FINAL: ASTONISHING CONTRAST IN BID FOR HISTORYAWER MABIL: SOCCEROO’S CLUTCH MOMENT SNAPS CUP CURSEIt’s no secret the club are leaving no stone unturned in their pursuit of an elusive Champions League title, and it appears their early exit at the hands of Ajax was the catalyst in this call.Therefore, the club will almost certainly be keen on finding a replacement with pedigree in the competition.Mourinho fits the bill best having won it with two different clubs, although if Pochettino gets the job done this year his stock will surely rise remarkably.Antonio Conte is available and has been linked with a return to JuventusSource: APThen there’s the matter of where Allegri will end up.“Where will I go? Home!” he joked when asked his next destination on Italian TV.“Now I can go to the beach a little bit.”The 51-year-old has been perennially linked with some of Europe’s top jobs for years, and he now has the opportunity to explore his options.It’s a massive few months for the world’s top clubs, and we could well see a footballing musical chairs between a number of top managers.Watch this space.
