Not really Drago.
Mourinho was in communication with Zanetti who had informed Zhang that he's available to join at the end of the season.
Ausilio wanted Spalletti to be sacked immediately. He considered Cambiasso as a caretaker (assuming he spoke with him and Zanetti first).
Marotta was clear on Spalletti not getting the sack and finishing off the season. He then held talks with Conte who said he'd be willing to take over instantly. Assuming there would be no expectations to reach a Champions League spot. So Marotta was then willing to give Spalletti the sack but at the same time found a great opportunity to get rid of Icardi by taking advantage of the Spalletti-Icardi feud and escalating it to boiling point.
Marotta also held a meeting with Mourinho and they discussed things. Who knows what exactly, but for sure no one told him at the time that we were not interested in him and we have other priorities.
Zhang then intervened and did not want us to sack Spalletti (cost) and hire a new manager with high expectations and salary. And Marotta did not want a novice to finish off the season.
So he essentially agreed with Conte to take over at the end of the season, no matter what, which is also a reason for his extremely high salary as he was prepared to sign for a Europa League team.
Mourinho actually refused several offers because he was waiting for Inter. Granted, he was also waiting for Real Madrid but at least they had informed him that they didn't want to go for him at that stage.
Marotta pretty much handled the whole situation by himself despite pressure from within the club to bring Mourinho back. That's exactly what he did not want here. Mourinho would have been much bigger than him and any success with our newfound 200m budget would go to Mourinho and not Marotta who would be in the shadows whilst Mou would have kept Icardi and Nainggolan around for sure, so Marotta would have been undermined. Conte on the other hand just wanted to return to coaching, get a big fat salary and has zero bond with Inter to care about who he's going to throw away in the process and only had a specific number of players he wanted to bring over. Which we did for him. Lukaku, Lazaro, Moses, we kept Candreva and Gagliardini for him, bringing him over Giroud and tried to get Vidal. And he's now complaining to the management that we are bringing Eriksen over against his recommendation
Mourinho leaving Inter did not feel nice, but it felt like a chapter closing. He did not really abandon us, his move to Real Madrid gave us 25m as well which was enough for a world class player at the time.
