I think that Roma's complaints in the domestic league cannot be used as a reference. I saw the Bayern Leverkusen vs Roma match. The overall strength of the two teams this season, Roma has indeed experienced an increase in quality since being coached by De Rossi, but I think they are still not stronger in comparison. Bayern Leverkusen.
For the Atalanta vs Marseille match, of course Atalanta is very much the favourite, they have very high self-confidence after successfully beating Liverpool.
Too many people rooting for Atalanta, bit I don't see them in the UEFA European Europa League Finals. This is my opinion, but we will see what happens.
For the past days, all I have seen high in my head is a finals between two team mates from Arsenal. ( Granit Xhaka and Per Emerick Aubameyang ) as they both had internal issues with the club and also with the fans.
Since leaving Arsenal, they have come a long way, I hope to see that finals. Per Emerick Aubameyang has been instrumental for his side honestly with goalscoring and assisting, Sincee they're far from qualifying for the Champions League Competition next season, they will go hard to win the European Europa League Finals.
I don't want to talk about Bayern Leverkusen, too quality players, staffs and manager, we all know who's gon make it up to the finals..
