Regarding Cavani, gazzetta didn't say there was an official offer, it was just speculation.
And about Isla and Asamoah, the co-own of 9M and 9.4M will be paid in 3 years installments - so what was actually spent this year was 6.4M for both.
Also, Giovinco's fee - 11M - will be paid in 3 years installments
Giaccherini's 4.25M will be paid in 2 year installments
Leali - 3.8M in 3 yrs installments
Caceres - 7M outright.

So technically Juve has spend, this year, 6.4 + 3.7 + 2.1 + 1.3 + 7 + 0 + 0 = 20.5M for players - Isla, Asamoah, Giovinco, Giaccherini, Leali, Caceres.
If you take into account other financial commitments who will come into effect the 2012-13 season, as:
Padoin: 5M in 3 years - so, 1.6M per year
Elia: 9M in 3 installments - the last installment is of 2.5M in january 2013
Vucinic - 15M in 3 years - so 5M this season
Vidal: 10.5M in 3 installments - 5.5M due this year
Litch - 10M in 3 years - so 3.3M this year
Matri - 15M in 3 years - 5M this season
Quagliarella - 10.5M in 3 years - 3.5M this season
Pepe - 7.5M in 3 years - 2.5M this season
Motta - 3.75M in 3 years - 1.25M this season
Krasic - 15M in 3 years - 5M this season
Damn, if u look at the full price of Matri - loan + installments - it's 2.5 + 15 = 17.5M. Quagliarella: 4.5 + 10.5 = 15M

So technically, Juve's financial commitments this season so far are 20.5M for the new players + 35,15M of transfers carried out in past seasons = 55,65M.
The website doesn't say how much Melo, Diego and Sissoko's fees Juve might still have installments to pay... so the total could be bigger.
Shit!!! It's a lot of cash.
