these are the players that were signed this season:
Tiago (Lyon, £8.74m)
Vincenzo Iaquinta (Udinese, £7.44m)
Jorge Andrade (Deportivo la Coruna, £6.77m)
Sergio Almiron (Empoli, £6.05m)
Christian Molinaro (Siena, £1.68m)
Hasan Salihamidzic (Bayern Munchen, Bosman)
Momo Sissoko (Liverpool, Undisc. rumored to be about £13m)
Zdenek Grygera (Ajax Amsterdam, Bosman)

The sum of all these transfers are about £44m or something like €57m. As far as i know the transfers of Iaquinta, Andrade, Salihamidzic and Grygera were all done by Moggi and not Secco (I'm not sure about Molinaro, but I will count him as a Moggi transfer). Out of the total of £44m Secco is accounted for about £28m while Moggi spent £16m.
Meaning Moggi spent less money on more players than Secco, so the argument that Secco goes for cheap players who end up being bad is totally wrong. Problem seems rather he has no clue which players are good or not. Although, that said, I find it very doubtful that he makes all these decisions himself, surely he must have scouts working for him to tell him which players are worth buying.
Since I don't know all the details of how much calciopoli affected Juve i can't say for sure, but maybe many of the scouts also left Juve (and other staff members) because of calciopoli and so it would be unfair to lay all the blame of bad signings on Secco. But obviously since he is the guy in charge he certainly needs to take responsibility and should go given the bad results.
I just want to make one more point. It seems now that Juve are not as interested in signing Diego of Werder Bremen anymore, mostly because they can't afford him. A signing that at least many of the fans seemed to have liked. One of the problems of that transfer was that Werder wanted something around £25-30m for him whilst Juve wanted to give less.
Had he not signed Tiago, Almiron and Sissoko they actually could have afforded him. I'm just saying...
