Righteo antohan, sorry for not responding sooner but I'll address some of your points. Firstly there is nothing inherently wrong with a 4-2-2-2. People have raised the same concerns about the diamond and the 3-5-2 in these drafts and as always, if you have the correct players there is never an issue.
I personally love this formation and it's capable of playing the exact type of football that I would want to watch, particulalry with wonderful passers like Bochini and Totti at the heart of it. In certain situations it lacks width but with Rivaldo, Totti, Cafu and Elkjaer there are numerous players capable of moving wide - most of those have done exactly this in narrow systems throughout their career.
I completely disagree with you on Bochini needing to go - I don't think it's a bad idea, but I don't think it's necessary either. Both work fine, this works fine. Defensively I think there is already enough there. In Passarella and McGrath we have quite comfortably the better centre back pairing and then in front of those are two midfield monstrosities in Sammer and Souness.
In Passarella and Sammer we have the two best defensive players on the pitch. Both have a huge role to play which is what you want to ask of great players - I remember you saying this yourself. I just don't see a problem anyway - Bergkamp is Harm's most creative player and I think Sammer will do a far better job limiting his influence in that area than Bonhof will do to Totti or Bochini.
I think some of the views you have put forward are not at all balanced. As has been pointed out by a few people, Falcao and Neeskens charging forward is going to leave gaps for that front four of Rivaldo-Totti-Bochini-Elkjaer. And that is a fantastic front four. It offers more threat in attack than Harms does the other way. It would leave Harm's completely exposed to the counter and there are numerous issues there - not least the fact that in Passarella and Sammer there is excellent distribution from the back. Both of those can immediately instigate attacks from deep.
You're just offering an imbalanced account. Highlighting the threat of midfield runners and then completely ignoring the space that leaves going the other way. Totti only needs a second before splitting a defence with a pass, I've already mentioned how Elkjaer would be a nightmare running at Ruggeri, and then most of all Rivaldo pulling into that space abandoned by Kaltz is guaranteed to create chances.
