Not that i necessarily disagree with it but how does that stand with letting Dybala go for free and then investing as much as we are rumored to in a Berardi or a Zaniolo? How come we have the money for that but when it comes to Dybala we had to choose between renewing him or not getting Vlahovic? In my opinion we could have easily kept both if we really wanted to but clearly Dybala forced the management's hand and they made an example out of him by not renewing his contract and kicking him out, which at first sight looks like the right decision for everyone concerned, however in hindsight letting him go for free to then just go on and invest close to 40M on an inferior player that could just as easily be a flop here might eventually turn out to not be that smart of a move afterall.
It's very subjective anyway.
There are aspects beyond the money at play. For example, yes the money could be similar (we don't know and rumors don't count for much) but is the outcome the same? Dybala has had awful injuries these last few seasons and so has Zaniolo (don't get me started on him). But one is young and the other is not. That type of circumstances doesn't get any better. Dybala also was not doing us any favors tactically.
Let's be honest, for all his amazing play, Dybala has been a tactical nightmare most of his career here. And hats off to him for his performances in such a situation but he is a classic second striker in a era of wingers and 4-3-3 and 4-2-3-1 formations. How do you play him with Vlahovic and Chiesa? It was hard playing him with Ronaldo and Morata and Chiesa not due to a crowded attack but due to how the other players are fielded and how Dybala MUST be fielded himself. He is better suited for a back 3 formation and we aren't there anymore. Berardi and Zaniolo bring far less of those tactical issues. Also, the wages when balanced against injuries. Berardi and Zaniolo will be no where near the rumored 8-9m wages Dybala wanted. Probably half.
I don't think Dybala was made an example of by management in the way you make it out. I think he was made an example of in the way that management said "listen, you're not worth 9m wages anymore, we know it, you know it, you won't work with us so we won't disrespect you by offering 7m wages." And that's entirely fair. He's not worth 9-10m wages. The problem with this era of players is contract extensions with teams almost always go up and rarely go down. And that can trap teams. Dybala at 9m wages is probably more of a trap than most people would care to admit. It's a sad state of things but it's the cold truth.
I do think Berardi at anything over 30m is way too much but he also has the numbers to back it up like Dybala. So how can Sassuolo ask for less? Zaniolo I am not a fan of based on his injuries but he has the hype machine behind him in Italy.
