AS Roma have accomplished a lot since appointing Jose Mourinho as manager; he's not GOD, but a genius who records both winning and losing, he knows how to manage a club. He pursues his ultimate ambitions and ensures that he meets the objectives he set for himself.
Jose Mourinho smartly chooses what is best for his club and he bravely sacrifices one competition to focus better on a more important one that he feels Roma have higher chance to win. He won UEFA Conference League two seasons ago and in the last season, he just failed in a Europa League final match at penalty shootouts.
I suspect why a club like AS Roma can only focus on one competition, that's why they are quite good in European competition, but in Serie A they are not that impressive because the material of their players can be said to be average or because their reserve players are not as good as the main players, so when their main players were injured or when Mourinho had to rotate, their appearance decreased very noticeably. The main reason why they are like that is money, AS Roma does not have a strong financial ability and this transfer season they only get new players on free transfers.
Because their squad is very slim and they got a lot of troubles with player injuries in the last season. In second half of the last season, many matches Mourinho only was able to reserve some young players on Roma benches. It's hard for him to keep Roma as competitive in all competitions with many injured and missing players.
The drama of Juventus affected his strategy for Roma too and very unfortunately, they could not win Europa League by series of inaccurate decision from the referee and VAR team in the final match.
This season, Mourinho will certainly try to make AS Roma more competitive, but with their situation in the transfer market, it is quite doubtful that something surprising will happen to the team coached by Mourinho.
Dybala will stay and Mourinho will stay at least to complete his current contract with Roma. I respect Mourinho by wanting to complete his contract as it shows his respect and love for Roma. He had some difficult seasons before joining Roma where he revives his career and now he want to repay it to the club.
