Turin
Most article's mention 2 pilots
One very experienced ( over 15000 hrs) and one less experienced ( but still very able). Did not see reference to a staff of three.
Given that it is reported that the senior pilot had attended some political event that day, - possibly even likely that he was getting some shut eye outside the flight deck.
As stated above have NOT seen any reference to 3 on the flight deck
Would you have three for a 6 hour flight?
