The renewal of a new contract with AS Roma is a sign that Dybala will stay next season, but the possibility of Inter Milan and Chelsea to sign him is still wide open. At least until the transfer window this summer officially closes, it is still possible for Dybala to move to another club. It's true that Dybala is an injury-prone striker, maybe this is the factor he refused to go to Chelsea.
Jose Mourinho has no other choice but to keep his star players from moving, because Dybala sales are not necessarily enough to buy other players at his level. The fact is that AS Roma is not a wealthy club like Man City in the EPL, which can easily buy players in the transfer market.
Dybala has found a comfortable form with As Roma so he has agreed to sign a new contract with As Roma until the 2026 season. So for teams that want to get Dybala in this transfer window, they will experience difficulties because the player wants to stay longer with As Roma. Apart from that, he was often injured but he was able to prove his best quality last season.
I'm sure he will continue to develop with As Roma in the next season because he has the full support from the fans or from Mourinho. So in this season's transfer window it seems that As Roma are not very active in bringing in other players because they lack the budget to recruit players in this transfer window. But seeing the opportunities that exist it seems that Roma needs additional players in sticker positions to strengthen into the squad next season.
