Liverpool have younger players than Real Madrid and has experience in the UEFA Champion's League final, this is a big plus for them going into the finals. I think Real Madrid's defense is not strong at all and the Mane and Salah will run riot at them. Real Madrid will have to depend on their old but effective players like Modric and the miraculous Karim Benzema to get the job done.
I think it's still not possible to happen especially when Madrid are ready in midfield.
For defense, indeed they are nothing special there but on the other hand when looking at their midfield movement I think they can still turn things around with this not to mention the movement of Vini and Benzema up front which has even made three big clubs like City, PSG and Chelsea so hard.
If you remember Real Madrid's matches against Manchester City and PSG, both won early in the first leg and only Chelsea won in the second leg but lost on aggregate.
and I mean in the Champions League final there is only one game and if the previous games against Manchester City and PSG happened to Liverpool then Liverpool would be champions, because Real Madrid can only turn things around in the second game or the second leg.
but these are the two best clubs among other clubs because the Champions League is the most prestigious league of all the leagues and there are only four best clubs that qualify for the Champions League, Real Madrid and Liverpool are the best among other clubs and it will be an interesting match and also very tight.
