Mandzukic was a big game player and can also play on the wing.
I don't understand sorry- do you think I don't realise this about Mandzukic? More pertinently he was the last guy who'd been seen as a winger until the necessity appeared. He was then able to work hard to make up for any technical shortcomings, and was perhaps the star performer in the best Juventus team since Calciopoli. That's the point I was making.
As for Dusan, if you're implying he's not a big game player I don't think that's true. 4 in 5 Champions League games this year including the opener against Man City and both equalisers in that comeback effort vs Leipzig. He's scored in a Coppa final, CL last 16 and a EL semifinal.
He's scored domestically against Inter, Milan, Napoli, Atalanta, Lazio and Roma in different games. He's missed just three pens for Juventus, and we won all of those games regardless.
There are definitely issues you can raise about Vlahovic's game but not showing up in big games is not one of them imo.
