Personally I don't care in the slightest about his past with Juventus. The issue with this guy is that he just isn't suited to the Inter of today.
Conte pretty much demands that he gets everything he wants and that it's the only way to succeed. He showed his true colours in his second season at Chelsea when even though the club backed him with over £100,000,000 worth of new players, they weren't the ones he wanted. Instead of getting on with the job and building with the squad at his disposal, he dropped tools and just coasted through the remainder of the season until he got sacked and got his £10,000,000 pay out, albeit almost a year later than he wanted it.
This also fits with why he didn't get the Napoli job. Aurelio De Laurentiis chose Ancelotti because when he was told he wouldn't be able to get all his transfer targets with Napoli's budget, Ancelotti accepted the fact and would work with the squad at his disposal, while Conte insisted on a list of targets, expecting Koulibaly to be sold to free up transfer funds.
He was used to getting his own way at Juventus where it's entirely possible for that to happen. At Inter, even though we're no longer operating under the settlement agreement, Ausilio isn't going to go out this Summer and spend 500m on new players that Conte wants. He has the thankless job of trying to improve the squad whilst also not getting us back under UEFA's microscope and into the situation Milan have found themselves in after their ludicrous spending spree.
Come September, in all likelihood, Conte will be like a child on Christmas that didn't get the toys on his list to Santa.
For me, with the set up at Inter we don't need the manager type in a Conte or Mourinho. A coach in the mould of Sarri is what we need at Inter. He doesn't wait for January or the Summer to try and find a solution, he finds the solution on the training ground.
"Transfer Market is the refuge of the weak. It is for those who can't train their players. I'm a coach. Give me a group of players and I will coach them." - Sarri's views of the transfer market.
