He was born in Alcamo, in the Province of Trapani, Sicily, and started his career at Campobello di Mazara in 2005–06 Serie D: in October 2005 he was signed by another southern Italy side Cosenza, also from Group I.
Thus, Rigoni was sold under the previous accounting price of €1M; and in accounting the transfer fee for the new signing (Di Donato) was amortized proportionally to player contract (5-year[2]), which the supposed €1 million loss in 2008–09 now extended to €200,000 a season from 2009 to 2014 and zero in 2008–09, but deducting wage (which Vicenza saved a season by lending) and VAT.
Moreover, Chievo also booked an exponential player profit on Di Donato in 2008–09 accounts.
On 1 August 2009 Di Donato was farmed to Valenzana along with Alessandro Lorello, however, he ran out of potential and only played 3 times.
Vicenza would have suffered a great loss if they immediately write-down his flopped value on 1 July 2010 (€800,000).
