AC Milan and AS Roma could be other candidates who have a chance to stop Leverkusen or Liverpool from reaching the final. AS Roma is now also a team that has experienced significant improvement after being managed by Daniel De Rossi, these two teams deserve to be considered a tough test for anyone who has the ambition to win the Europa League trophy this season. Liverpool deserves to be considered the strongest candidate among all the contestants, because it comes from the Premier League which is known as the most competitive league. Leverkusen is the most ideal team to be their opponent in the final match this season, because he has never been defeated.
I believe more in AC Milan than in AS Roma but I know AS Roma get good performances with De Rossi as their new coach. He is doing his job well with Roma but he has very little experience as a coach, less than other coaches in Leverkusen, Liverpool and AC Milan. It can be his weakness and can cost Roma in important matches.
Among four teams, Liverpool, Leverkusen, AC Milan and Roma, I would like to pick either Liverpool or AC Milan as best candidate to win Europa League. AS Roma and Leverkusen have good strength and can win Europa League but less than Liverpool and AC Milan. Leverkusen also will have to beat Qarabag in Germany to go to quarter finals and with a first match between two teams, Leverkusen will have to beat a tough opponent.
