What gives me hope that Zaza will turn into a top level CF, is the fact he has improved each and every season in Serie A thus far. I could easily see him turning into a Bayern-Mandzu level player. plus-minus 25 goals in all competitions type.
Zaza:
2013-14 (22 years old) - 2385 minutes - 9 goals - 265 minutes/goal
2014-15 (23 years old)- 2736 minutes - 12 goals - 228 minutes/goal
2015-16 (24 years old)- 943 minutes - 8 goals - 118 minutes/goal
Impressive improvement.
