Half of Berardi for 15 mil is great, because we didn't pay 15 mil for his first half. We'll have paid far less than 25 mil for a prospect who has easily shown as much as Dybala, if not more.
I've watched both of them play. Many times. More so Berardi, because no one on the forum, including you was watching Dybala sucking balls as a 20 year old in Serie B last year, while Berardi was running rampant as a 19 year old in Serie A.
If you think Dybala has been consistently good this year, you're off your rocker. He had one very good stretch. Much like Berardi's very impressive run over the last 12 matches. Outside of that both of them have been very inconsistent.
And if you think paying 30+ mil for a 21 year old, with 1 year of contract left, and 1 good but inconsistent season, is a good idea.
