Hyperbole much? Injured 80% of the time? Come on man. You're beginning to sound like the haters. I am all for selling Dybala, if quality reinforcements are brought in. That's a big IF. Selling Dybala to free up wages for Romagnoli and Scamacca is not progress or moving forward. That is regression.
If you free up Dybala's wages and bring in Vlahovic on 5 million and another quality winger, then so be it.
However, as things stand, the more logical thing to do in a rebuilding phase is to sell the guy who is most likely to leave and bring you the most money.
