Osvaldo only turned 28 two weeks ago. It's basically the identical move to Vucinic coming 2 years ago. We paid 15 mil for Vucinic at 28 and gave him 3.5 mil a year. 28 year old Osvaldo and 28 year old Vucinic are very similar.
Vuci last 4 seasons at Roma were 9,11,14,10 league goals. So 44 goals in 122 appearances in league play.
Osvaldo last 4 seasons (2 at Espanyol and 2 at Roma) were 7,13,11,16 league goals. 47 goals in 99 appearances in league play.
So actually Osvaldo goals per appearance are significantly better than Vucinic's in the 4 years before they each moved to Juve. SO if we paid 15 mil for Vucinic at 28, 15-16 mil for Osvaldo at 28 is certainly a decent deal.
