As far as I'm concerned a vice Dušan should be the number 1 priority this summer.
When we had a real striker on the pitch (which in our case is only Vlahović), we had 13 wins out of 23 (compared to Juve's total of 11/27). Our win percentage is 57% with a striker on, and the actual total is 41%. Without a striker it's 19%.
When a striker plays we have a goal difference 40:17 and we score 1.92 goals per 90 minutes. When we play without a striker our goal difference is 5:6 and we score 0.80 goals per 90 minutes (4 of these 5 goals were scored by Yildiz, and the 5th is Nico's masterpiece vs Cagliari in Coppa)
