It isn't just Jose Mourinho who has endured a miserable season - his band of protégés have also suffered...
"Intriguingly, Derby deny that their diminishing automatic promotion prospects caused the split, instead making the unusual accusation that Clement was too obsessed with short-term success and was straying from the agreed long-term strategy as a result."
Prior to this one, 2007/08 was probably the worst campaign across Jose Mourinho's two stints as Chelsea coach as he was sacked in September following a mere six Premier League games.
However, while it was one of the few that he would probably prefer to have stricken from his record, it was probably his peak in terms of assembling a backroom team so talented that many would craft their own managerial careers: Steve Clarke, Andre Villas-Boas, Brendan Rodgers and Paul Clement.
Their reputations were all elevated between the moment that Mourinho left Stamford Bridge and his 2013 return but, with the exception of AVB - who guided Zenit St Petersburg into the Champions League round-of-16 - they have all found 2015/16 as horrible as their former master. Observe...
Less than two years ago, Rodgers was upstaging Mourinho in his first season back in English football, finishing two points above the Blues with Liverpool, who he came painfully close to delivering a first title in 24 years too. That proved to be the high point of his time at Anfield though.
The Reds dropped to sixth in 2014/15 without Luis Suarez and exited the Champions League in the group stage, and then axed him after a middling start to 2015/16, albeit one in which he averaged more points per match than his successor Jurgen Klopp. He claims to have received job offers since, only to decide to hold out until the summer.
Mourinho's original Chelsea number two was the one who most had the highest hopes for. He got his first shot at running things at West Brom and initially thrived, achieving their best ever Premier League finish by placing eighth in 2012/13 and doing the double over Liverpool along the way.
The second season didn't go so well, but it was still a shock when he was sacked in December with the Baggies in 16th place, the theory being that prior complaints about transfer activity weakened his relationship with the board.
A lack of managing-up savvy also hastened his demise at Reading this term. A run of six wins in seven between August and October led them to second in the Championship, yet his public negotiations over the Fulham vacancy soon after sunk his approval rating and, even though he opted to stay, it went down poorly and he was replaced swiftly once form dipped.
Clement is known more as a Carlo Ancelotti guy than a Mourinho man as he was a mere youth-team boss for the Portuguese coach, whereas he worked with the seniors under the Italian, who took him to Paris St-Germain and Real Madrid afterwards, but he had the chance to learn from Mourinho too.
The 43-year-old was the last of this group to go solo, taking the Derby job last summer following Ancelotti's Real Madrid departure. There were three phases: the awkward opening (winning none of their six August games), the excellent end to 2015, (losing just once in 19 fixtures from September to December) and climbing from 19th to second and then the New Year blues (dropping down to fifth).
Intriguingly, the Rams deny that their diminishing automatic promotion prospects caused the split, instead making the unusual accusation that Clement was too obsessed with short-term success and was straying from the agreed long-term strategy as a result. Academy chief Darren Wassall has been put in charge and is [1.55] to last the ten league matches needed to trigger a next manager payout.
