Tuttosport have examined some the key moments that saw Stefano Pioli’s tenure as manager of Inter end on Tuesday night. Up until mid-February, Pioli had an average of 2.38 points per game, the highest of any manager since Jose Mourinho’s time and everything was going right. The recent Inter capitulation in the last ten games has seen his total drop to 1.65 points per game.
Big games always proved a problem for the former Lazio manager, which included defeats to Napoli, Juventus, Roma and elimination from the Coppa Italia to Lazio, who’ve went on to the final and will play Juventus.
Moreover, the likes of Gabigol and Joao Mario, two of Suning’s first purchases at Inter were used sparingly as he preferred to rely on elder statesman such as Rodrigo Palacio instead.
Finally, Pioli lacked motivation and control. When the going got tough he lost control of the team and couldn’t get them back on track which ultimately cost him his job.

Dont know why palacio still playing. He is finished.
Wasn’t Banega Thorir/Mancini signing? I didn’t like Pioli’s all defense after 60 minutes at the derby, but I believe had he been a bit luckier and that extra extra time goal from Milan hadn’t happened he would still be Inter’s coach. After that everything fell apart, although loss to Sampdoria was an early warning sign. Derby win could have been a motivation boost for our weak mentality lazy squad.
His downfall started at Inter-Rube game.
At that point we were steamrolling everyone with our 4-2-3-1. In that game he switched to 3-6-1 for no reason, and we lost the game. Same goes with the Milan game. When you are a coward as a coach you send negative vibes to your team, and suck motivation out of them.
I compare him with Allegri. Allegri stuck to his 4-2-3-1 with Mandzukic (a ST as his LW) even against Barcelona. The difference is Allegri had balls and Pioli didn’t.
Steamrolling everyone is a bit too much to say, although we were doing good. Like away against Udinese we were really lucky to win when we pretty much should have lost. He used his luck and as you said lacked them balls also.
The lucky ones were his first few games. The later ones we were playing well AND scoring. Like the one against Atalanta for example. The message you send your players as a coach is crucial. Against Rube he said no matter what, even if we are on a better streak that Rube, I’m gonna lose my balls and put three in the back.
But those Atalanta (7-1) and Cagliari (1-5) steamrollings happened after losses to Juve and Roma so surely he still had things under control after that Juve loss? The win streak was before the steamrollings.
I argue still that the Milan loss was the point where Pioli lost control and players motivation. Those first 60 minutes in that game is the last time I remember our team has played quite well.
