Its more like anything he touches will be heavily scrutinized, and that he is literally prohibited from making deals in Italy.Why shouldn't he be trusted? Paratici has not done any "fishy" deals while at Spurs and when he did it at Juve the club was in on it.
I thought Levy would have fired him by now just for the PR image aspect, but, if not, I'm still plenty interested to hear who Paratici thinks is a good signing. He might be crooked but he certainly has a legitimate awareness of who is a quality player and who is not.
