The situation with Mourinho is entirely different. Mourinho was backed, more than enough. His transfers were just bad on average. Furthermore, he was having an absolute meltdown, bickering with players, laying on them in the press, etc. Conte is not that type of character. If he disagrees with the board, he'll air his concerns about "not being backed", but he won't go against the club or against his players... ever. When he left Juve and Inter it wasn't like he lost his mind, he simply said he wasn't backed enough and couldn't get Juve (or Inter) to take next level, so he left. Totally different characters.
