I'm thinking we can't have a "nice guy" (like DD) in charge, knowing that we will have everyone and everything working against us. Media, rival fans and officials will put tremendous pressure on our team. Everyone will want to be able to say: "see, they can't win without the help from ref's".
Therefore, Mourinho is perfect, he's been working under similar circumstances with Chelsea and done well.
With that said, thank you Didier for everything. A true Juventino you are.
