The motivations of the judge (some pieces here
http://forum.j1897.com/index.php?showtopic=25091) say that in the phone calls, there was nothing illegal or that lead to think we could control refs. This is the most reliable source.
What we read on papers are some conversations with paieretto, some private conversations (!!!!!), a conversation of Pairetto (or Bergamo) with Dondarini, the ref of Samp-Juve last year.
After the match the ref says "the penalty against Juventus was so evident that I couldn't not concede it" " in these cases you can't award a penalty, because it's a big team" "After I awarded the penalty to Samp, the linesman called me and said it was not a penalty, he had made a mistake. I answered him that I had already awarded it, it was better letting them shoot it anyway. But he answered: no, look, that penalty is a joke and if we let them shoot it we're gonna sputtanarci (something like make a fool of ourselves) in the most incredible way"
This would be the influence of Moggi on refs? Dondarini was afraid of awarding us a penalty!
