I agree with you. Dybala should stay with Mourinho. Mourinho is an excellent coach. And he is very aware of the players in his squad. He developed a friendly relationship with the players, and he knew well how to handle a player.
That's why Dybala still wants to stay at Rome, especially since his contract is still quite long. Even to ward off various rumors about his move to other clubs, finally Roma has also signed a new contract with him, to avoid rumors of Dybala's release and also to keep the forward. yes, indeed the strategy and method of training Mou had quite an impact on the progress of Dybala's performance. His performance is getting better and even becoming one of the key players in Rome. it's just that at that time, Rome really needed a few more better players so they would be even stronger. Like midfielders and defenders. And now they are doing it with some new signings.
