First of all, I apologize in advance for my english mistakes i surely will do writing this. I'm italian and juventus' supporter.
And I better clear I love Antonio Conte's way to play much much much more the Allegri's one.
I decided to write beacuse I read something partially right on what happened back in juventus days.
He took an average team to 3 Scudetto in a row, anyway the board and him never got on well.
After first Scudetto he pretended a team ready to fight for winning CL. Board had different plan. The plan was step by step, year after year.
In 2012 he was accused not to report a fixed game he was aware to, when in 2011 was Siena manager.
He was charge with 10 months ban. He denied, he wanted the trial. Juventus wanted him on the guide as soon as possible, so persuaded him to "negotiate a plea bargain" (not sure if is correct in english). He did it and the ban was 4 months but Conte never forgave juventus board to make him look guilty.
As someone said before, his third year, lost in Istanbul on a pitch not good for rugby. Players had not enough self esteem to play CL at high level, not Conte fault then. That year juve had a really good team, one of the best in europe : buffon, bonucci, chiellini, barzagli, lichtsteiner, vidal, pirlo, pogba, asamoah, tevez, llorente/vucinic.
Here is where something starts going really bad.
Juve is in EL, that year final was gonna be played in Turin (at home)!! Juve easily went on semifinals, Benfica-Juve 2-1 and Juve-Benfica 0-0 meant no final.
One can say, yeah it can happen, right but the problem is players played those two matches tired, really tired because Conte wanted more than anything else to make more than 100 points in the league. He did it: 102, record likely will never be beaten.
The man pushed to much, that wasn't wise, everyone knew but him.
He wants 100% every match, from begging to end, wonderful to watch, I appreciate that, but has consequences.
At the end of the season rumors says he went to the board, said many player were old and after 3 years like those couldn't be at the same level (motivation and physical), so the next year he left the board two choices.
1) another year with those old players and buy some top players to win CL
2) sell the old players and restart with a new young team with no pressure from the board to win the league soon again.
He waited since July!! and then decided that the board (which was not agree with him old players couldnt continue some years at the same level) didnt make enough to figth for CL and left.
That year Juve bought Coman, Pereyra, Evra, Morata. Board went its way, step-by-step. What we know is that Evra and Morata were Conte's choiches. My speculation is that Conte got angry with the Morata affair. Juve bought Morata with 'recompra' clause meaning in his eyes juventus being a real madrid 'B team' not a contender.
Board pretended to, yeah, listen to Conte but then buy what they wanted. Conte wasn't always right, he wanted Giovinco back in Juventus (similar affair ManU-Pogba) for a lot of money and Giovinco never was good enough, and all juventus fans already knew that.
After he left Juve made two CL finals in 3 years with the old players he said couldnt last some more years at the same level.
Conte wasn't always rigth.
Conte and the board separated in the worst way possible.
Inter.
I do not think he'll move to Inter next year but...
1) He said once he's a professionist and will not be a problem to be even Inter's manager
2) He appreciate Sabatini and he wanted to bring him to Chelsea
3) Take revenge on Juventus' board.
4) a lot of money
I can tell you, if he'll stay to Chelsea this summer he'll pretend Morata and Naingollan or Vidal. Why am i sure?
He sometimes got obsessed with some players, for example he loved Giovinco, Giaccherini not two players at juventus level, and got angry when juve sold Giaccherini.
He's the best one but he think he's always right and no one is.
