The Zaza to Juventus deal was a weird one, tied up in Italy's co-ownership stuff. As I remember, Juventus got him from Sampdoria in 2013, possibly for around £3 million, but then immediately sold off 25% of him to Sassuolo for £2.5 million. A year later, Sassuolo paid a further £7.5 million to own him outright, but Juve could buy him back for £15 million if they acted before the end of June 2015. They did that, but then also transferred Domenico Beradi back to Sassuolo as part of the deal. It's a weird one.
Anyway, no Juve seem to have decided he's surplus to requirements (only two months after buying him) and West Ham have bid £3 million for a loan with a £15 million agreed fee at the end of the year.
And people still claim Italian football is rife with corruption.
