Yes as you mentioned, target to the final is not easy, many aspects will be faced Liverpool because all team on champions league have the same target. Liverpool have to focus and keep consistent if want dream come true. Beside that Leipzig is not weak team, even they have never won on champions league, but Liverpool must not underestimate them because when they make a small mistake on the field that advantage will take Leipzig to beat them on their home. So I think liverpool will have a hard work to winning this match because most likely Leipzig will make tight their defense, and a draw is mostly possible if liverpool lack of attack.
The UEFA Champions League is no average tournament but mainly for elite clubs. We're talking about clubs that can stand boldly and face oppositions without having to shiver or frighten. Arne Slot have improve all-round standard performance for the club, he do deserves some accolades and have been an impressive manager for the club and the fans. He's loved by all based on the incredible stats he puts out there, his future is secured at Anfield. Liverpool will do what they have to do for the purpose to move next phase of the UEFA Champions League.
Moreover there's actually no room to underestimate any oppositions because these clubs have been majorly top and will always remain tough to handled, you know the direction I'm going. Teams like RB Leipzig didn't qualified for the UEFA Champions League by mistake or luck, they worked hard and earned their points, so they're consider elite club and their opponents should apply extreme carefulness to stay fit and strong enough to face them.
