I think Mourinho's quality has been declining for a long time, because before Mourinho coached AS Roma and the truth is Mourinho has failed to deliver good results at several clubs before. So, even though AS Roma is ready to buy some good players in the upcoming transfer market, but I personally don't believe Mourinho will be able to make AS Roma better and stronger.
But apart from that, of course, at this moment Mourinho just needs to focus on finishing the season well. Because after all, at this moment it is also a fact that Bayer Leverkusen is not a weak team because yes, Bayer Leverkusen has managed to improve so rapidly in the Bundesliga as well. Therefore, AS Roma does not have a big chance to qualify for the final, because of course Bayer Leverkusen will try their best to qualify for the final and this match will never be easy for both of them.
Mourinho has achieved much with an average team. Roma's current biggest signing is Tammy Abraham costing the club £40m. And with average spending the Special One won UEFA Europa Conference League last year and they are in the Europa League semifinals. If Roma feels that he has not done much, let him be sacked. Mourinho will not last one season without a job because he is one of the best currently in the world. If the club invests more in quality new signings, Jose has the ability and experience to manage them.
Leverkusen is occupying the sixth position in the Bundesliga while Roma sits at the seventh position in the Seria A, so I agree that both of them are in the same class currently. Both teams can win this game so the match is unpredictable but Leverkusen has scored twenty-four goals in eleven games making their attack one of the best currently. Roma has not also done badly with nineteen goals in eleven games. So we are expecting to see an attacking game that will produce a high number of goals.
