In my opinion, Roma next season will be different from Roma last season, although at that time Mourinho entered in the middle of the season but he was able to maximize his modest players at that time but unexpectedly won the Conference league title, seeing Roma maneuvers this season in the transfer market, of course Roma will be better next season and I think for the current striker position it is enough because apart from dybala and tammy, Roma also have some other good strikers at the moment.
I do not share your optimism, Roma in this transfer market has not received any significant increase with which it could reach a new level. I'm not even sure that Dybala will be able to somehow significantly strengthen Roma's attack, he is certainly not a bad forward, but he is not a leader who can lead a team or a forward who can score in every match. And hoping that Mourinho will be able to create a miracle is also not worth it, this requires large resources, this has already been discussed more than once.
