I remember a period where many wanted Lippi's head in his first few matches as coach. And then it went from wanting his head for incompetence to wanting his head over calciopoli. And all the incessant, hyperactive coaching diddlers looked like complete fools in the end. And believe me, as much as I like Lippi, he was hardly Italy's coaching messiah as some have since made him out to be. (By rights, the team won the final in spite of him.)
The Inter comment is a reference to people with too short an attention span and too low a commitment level to let a program gel over time instead of looking for quick, flashy fixes overnight. Because Inter is loaded with a history of proof of how seeking the quick fix gets you nowhere but the laughingstock of Europe. Inter wouldn't bring in Donadoni -- no, they'd bring in Capello, fire him after a few months, and replace him with another fool with an expensive pedigree. Meet the new boss, same as the old boss.
I don't think Donadoni is that great a coach. But he's not that bad either. And Italy isn't as good a team as their WC trophy might lead some to believe. (This is a team that drew to 9-man USA and almost blew it against Australia, afterall.) But that is probably to be expected of every great football nation: anytime you lose points, its a crisis.
But the reality for many fans of the Italy NT is unfortunately this: without a calciopoli scandal to motivate players, etc., it's going to be a long many years of Totti spitting ejections and mediocre play that will make everyone want to behead whatever coach X is in there until they win their next major tournament.
Snoop, make the odds and I'll put all my vCash on it. In the meantime, I suggest a great many of you start upping your anti-depressant medication regimens now, because it's going to be a long road unless you can graduate from denial to acceptance on this one.
