Real Madrid played PSG, Chelsea and Manchester City to the finals I think Liverpool won't have survived if they had faced those teams.
Irrespective of the age and experience of the Madrid team, I think the club itself being a big club has a role in playing how formidable the team have been. Liverpool team is quite younger, majority of them have been playing together for a while too. The difference between them and Real Madrid will be strong character and mentality.
That's right, Real Madrid have beaten strong teams to be in the final, PSG, Chelsea and also Man City. in terms of quality maybe Real Madrid lost to them it was evident in the game in possession but the mentality of Real Madrid was able to make them turn things around, therefore I think Real Madrid deserve to be champions of the UCL this season, after what they went through. it's very worth it.
