AS Roma, Bayer Leverkusen and Liverpool managed to score quick goals in this match, they played at home and seemed to maximize it so much because they managed to score quick goals in the first half. Their scores at half time is AS Roma 2-0, Bayer Leverkusen 3-1 and Liverpool 3-1 so obviously, those are great scores and results of course.
Bayer Leverkusen already scored 5 goals. Meanwhile Liverpool and Roma still lead the matches with the the scores you updated above. I think they are quite satisfied to win the matches with that scores. However, I expect Liverpool can score more goals, they still keep some strong attackers in the bench (Salah, Gakpo, Szoboszlai, Mac Allister, Diaz). If Klopp lets these players to play, I'm sure there should be more goals for Liverpool.
Anyway, I think these 3 teams are the favorite teams to be in the final round. They always win the match, they are leading their groups perfectly. Personally, I expect Liverpool vs Bayer Leverkusen in the final round.
I was wrong in my prediction about AS Roma because I thought, it seems AS Roma is not easy to win in this match. But in fact is, AS Roma played a quick goal in the 1st minute in the match and of course, made Slavia Prague certainly under great pressure at the moment.
Why do you think it won't be an easy match for AS Roma?
AS Roma has stronger squad, they also play at home. There are no reasons for AS Roma to get difficulty in this match.
