In general I agree that Roma does not have the right squad to be considered a serious gold contender, but on the other hand, if we remember the exploits of Mourinho, then he does not need a super squad to achieve big goals.
I agree with you. Roma's squad may not be weak. But they do not have a strong squad to win the title. The team still has several weaknesses. But their performance is stable. In every match, Mourinho adjusts his match strategy by judging the strength of the opponent. And Roma is performing well in almost every match. If Abraham, Dybala and Zaniolo have better chemistry, the Roma team will be stronger. Roma's defense has been very strong this season. They did not concede a goal in any other match except against Juventus. Roma is a worthy contender for the title this season, even if the squad is not very strong.
