We can't really argue which club is going to win the competition because Leverkusen and Liverpool have never met. I hope it will come true soon. Only if Leverkusen and Liverpool consistently win the game in the quarter-final.
That's gonna be the first time leverkusen to play against liverpool.
How you can be so sure? if Liverpool can lose against Manchester United, there's a chance Atalanta can beat Liverpool. If Leverkusen almost lose against Qarabag FK, West Ham might able pull an upset. That's gonna be the first time leverkusen to play against liverpool.
Most of the times Europa league is full of surprise, so predicting the final match or the champion is kinda hard. Probably Roma will become a champion in this season.
