The Europa League clearly has differences with the domestic league, but we can assess a team's performance there.
In Europa League, which uses a knockout system, anything can happen and even luck will be quite influential here.
There's nothing wrong with predicting Liverpool and Roma's final, because both teams have good quality, but it's not easy and I really don't think that the course or what happens in the Europa League will be in line with what many people predict.
Now as we have top eight teams left into competition things are looking competitive and predictions are going to be tough with any team can win and go through for the next round if we will have Liverpool vs Roma in final this could be not surprising because Roma already lost last year into final and Liverpool current quality and performance is at the top which can give them good chance for reaching into last four.
We have four games into this round with all teams are good and having consistency which allow them to reach out here even few are looking stronger due to their quality and recent performance but still in UEFA events we can predict about any match with any game can go into either way with the match day performance of any team.
