Antonio Conte and Chelsea took much more time than initially thought, mainly due to the compensation problems solve
However, for the seventh time in a decade, Chelsea is changing her manager.
Conte delivered two trophies in two seasons. The former Italy boss led the Blues to the Premier League title in his first season, but the FA Cup was considered a poor performance last season.
Conte's winning percentage was greater than anyone who has spent more than 40 games at the club since Avram Grant left in 2009, but it was always a premature departure for the 48-year-old former Italy player. Juventus, explains Simon Stone of of BBC Sport.
Has he been the "true" Conte? 19659007] Warnings began to arrive even before Conte defied expectations of winning the title in his debut season.
A group of Italian journalists had joined the former national coach to tell their time at Stamford Bridge for an expectant crowd at home.
They had been surprised by Conte's smiling and jovial attitude.
This was a man known for his short life, who resigned in Juventus a month before the start of the 2014-15 season, furious over the club's failed transfer policy, upset by his preseason schedule and angered by those who they exert influence behind the scenes.
In that brilliant first campaign in London, Conte's only significant problem came with former Chelsea boss José Mourinho, who was angered by what he perceived as the Italian's excessive celebrations at the end of a home win over 4-0. United Manchester.
The Italian contingent told Chelsea members that, with a flammable figure like Conte at the helm, serenity could not last. It was not long before it was shown that they were right.
Where did it start to go wrong?
Almost everyone in Chelsea recognizes that, as manager, Conte was within his rights to decide that he could manage perfectly without Diego Costa.
The Spanish international may have scored 52 goals in 89 appearances in the Premier League over a three-year period in which the Blues won two titles.
He may also have been one of the most feared forwards in the English game.
But Costa was notoriously difficult to control and it was reasonable that Conte did not want to extend his employment relationship beyond a single season.
What surprised and enraged the Blues hierarchy was the method by which the manager told his player they no longer needed services: a text message, which Costa made public in June while in international service with Spain.
In addition to any damage inflicted in terms of the position of Chelsea, financially it was a disaster because Costa made it clear that he would not go anywhere, apart from his former club, Atlético de Madrid.
The negotiating position of Chelsea had been eliminated. The player went on strike while clubs bargained, and it was September before a 57 million pound deal was concluded.
In the middle, Conte had signed a contract of his own: an increase in salary as a reward for the success of his title. Interestingly, it did not extend beyond the remaining two years in its initial contract.
These two factors ensured that the first weeks of Chelsea's Premier League defense were played in a context of negativity regarding the manager's future and their cold relationship with senior players.
Conte's relationship with the rest of the costumes?
The dispute with Costa was only the beginning of Conte's slowdown in relations with his squad. Midfielder Willian is recognized as one of the most popular, calm and relaxed members of Chelsea's team.
When the 29-year-old Brazilian scored Chelsea's final victory in the FA Cup on May 19 on social media, he did so by posting an image of the entire blues squad and the backroom team at the Wembley field with The trophy, but completely covered the image of Conte with three cups of emojis, one on top of the other.
In public, Chelsea did not respond. Privately, they thought that if the relationship between Willian – the player of the year for Chelsea players last season – and Conte had collapsed to that point, how bad should they be with other more intense figures within the squad?
Although he has been eliminated with knee and ankle injuries in the last three months of the season, his compatriot David Luiz started only four games in three months After questioning Conte's team selection before the Champions hammer of the league for Rome on October 31.
Adelante Eden Hazard, a player that Chelsea is desperate to maintain, has had his commitment questioned.
Then there's the training, with Conte insisting on driving his players hard through his physical majority. The most demanding period of the season, when he felt all they really needed, was to keep up. The decisions were not explained.
Even during the two periods of Mourinho in charge at Stamford Bridge, it was certain that, although the Portuguese had a harshly routine face when they were in the media, behind the scenes it was very different and had a funny side He kept coming to the surface, routinely playing tricks on the staff members.
Conte had none of this. Sometimes he did not even talk to his own coaches, and almost never to his players. There were no arms around the shoulder or words of comfort in times of professional problems.
There has to be distance between a manager and his players. This has been more like a schism.
Where does the power reside, and why?
There are many voices in Chelsea. There are President Bruce Buck, CEO Guy Laurence and directors Marina Granovskaia and Eugene Tenenbaum. But only one voice really matters, and that belongs to the owner Roman Abramovich.
The Russian billionaire has had problems with the renewal of his UK visa, but any idea that this would be an impediment for him to get rid of Conte's services was preposterous.  The Italian is the tenth manager from whom Abramovich has undone. He has done it face to face once. Decisions are made quickly. Implementing them is a simple process.
And while Manchester United under Sir Alex Ferguson and Arsenal, initially at least, under Arsene Wenger underline the success that can be achieved by staying with a man, Chelsea's alternative approach has not prevented them from becoming the most successful club in England since 2005, winning 15 important trophies.
The equation for Abramovich was double.
First, did you think Chelsea would improve under a manager about to enter the last year of his contract?  Second, knowing how difficult some of the relationships had become, was he prepared to subject his players to the same kind of turbulence they had experienced in the past 12 months?
The answer was no.
What happens now?
Chelsea fans sang Conte's name during the FA Cup final at Wembley.
However, there were some who wanted the Italian was fired after the 3-0 that hit Newcastle on the last day of the league season six days before, because they did not think their club could beat Manchester United with such low morale.
There is no reason to believe that they will not join behind the replacement of Conte, it is expected to be Maurizio Sarri, when the new season begins in August.
After a decade of spending the most money on the best players, there seems to be a new financial reality in Chelsea, with Abramovich demanding value in addition to success.
The net transfer expense of the Blues in the last five years has been £ 44.4m, compared to £ 112.6m for Manchester City and £ 87.5m for Manchester United.
Time will tell whether this means that more focus should be placed on using the growing number of promising youngsters leaving the club's academy: Chelsea has won the FA Youth Cup for the past five years.
If more confidence will be placed on players like Ruben Loftus-Cheek, who went to the World Cup with England. after a season on loan at Crystal Palace, instead of spending 15 million pounds on Ross Barkley, who did not go to Russia after starting just two games after signing from Everton in January, remains to be seen.
However, one thing is certain: Conte will not participate in the process.
