now SKY are saying Bettega could come back

Trying to calm the ambiance? I'd take him back but that won't change what we're seeing on the pitch.
Honestly, thats a good start.
Just think about it:
Pre 2006 -------- Post 2006
Giraudo --------- Coboli Gigli
Bettega -------- Blanc
Moggi ------------ Secco
Lippi/Capello ---- Ranieri/Ferrara
It is just a fact that the current management do not have any kind of experience when it comes to football compared to the previous one.
When you bring in a coach like Ferrara who has never coached a team in his life, you are investing in him. If they are investing in him they should provide the environment for him to improve, e.g. providing advisors.
Gilgi was an executive at IFIL and Blanc's relation with sport was in Tennis if I am not mistaken. This means the Secco is literally their football expert. Secco in the old management was the person who used to take the sub paper to the 4th official. Between a day and two he became juventus' transfer manager.
Whether you like the Triade or not. Whether you respect them or not. It is just a fact that their experience in football was maybe the highest in the industry.
Every winning club has this. When Barcelona brought in Pep Guardiola do think they left him alone? Ofcourse not. He has very experienced managers backing him up and guiding him through his successes.
Look at Milan, its true they got Leonardo, but they still have their experienced managers.
Now take a look at us. Everything in our management is new and inexperienced. This all adds up to what we are going through this season. Last two seasons the situation was less dramatic because Ranieri was an experienced coach. I am not saying I want him back, but he was experienced enough to deal with certain situations. Maybe if Ferrara was coaching under the guidance of a management similar to the Triade he wouldn't be struggling that much because of the advices and support he will be getting.
