Yes, they brought Quaresma and Mancini. Did they shine? No. Then Mou asked for Carvalho, Drogba, Lampard. Who did he get? So, listening to coach isn't always the right thing to do. Mou gained his respect, trust and everything by proving himself on the pitch. You said nobody get a single chance? Really? Benitez wasn't gonna get sacked if he could behave his mouth in a better way after the final. As for Leo, there is many stories about his leaving, but I believe he has flirted with PSG bcs there was no sign at all he was gonna be asked to leave. Then, Gasperini was just too stubborn with his 3 line defence and lost the team support. Ranieri has been given a full support, Ranieri is the only manager could survive up to 13 bad performances in a row under Moratti. If Moratti wasn't being supportive, Ranieri would be sacked 2 months ago and we would probably still in the CL.
The right coach is the one who can create a new team slowly and step-by-step. Change is not made in 1 night like what Benitez tried to do. We can't just ask everyone in the team to leave after they won us CL title. Change should be made by a long-term plan. Injecting new blood and replacing the oldies. It took 5 years to build the team that won us CL title. As MM said, we can't just play all youngsters, we need a balance, but since Mou left, there is no good understanding between coach and boards. The only one was probably Leo, but then he chose to leave. Then the mistake of appointing wrong coaches kept going.
But, it's true. Ranieri = cancer in the team. You don't believe, ask Chelsea fans and Jube fans. I knew it was wrong since the day he was appointed as our coach. He is no more than a third class coach. That was one of the biggest blunder MM has ever done in picking a coach. Probably, second to Lippi.
