My point is that if Liverpool can blow away Man City in the manner they did, Madrid can get it too.
I'm going to say how I honestly see things now.
Liverpool is a good side and their three strikers are very dangerous, but in terms of overall level they are one or two steps below Atletico 2014, Atletico 2016 and Juventus 2017 who defended way better while being very complete in attack as well. The good news for Liverpool is that Real Madrid is
today nowhere near the Real Madrids of those years either, either tactically, either in terms of vibrations or fitness.
Manchester City is obviously a very good unit and their campaign in the league has been brilliant, but until I see the contrary, and having observed how Guardiola has coped in Europe not having Messi, I find his approach has probably been too naive in the continent for years. If I knew what kind of Madrid we're going to see in the final, I could probably compare it to Manchester City as you did, but right now it's impossible to know that. If the best Madrid, or at least a very good Madrid, appears, they will most than likely win the final. If the best Madrid appears, the comparison with City doesn't make sense. Madrid have played 8 straight semifinals, and 4 out of the last 5 finals. There is a world of difference with City and Zidane is a more pragmatic coach than Guardiola. Conversely, if a not good Madrid is the one taking part Liverpool will make them suffer and push them into trouble.
I also think, a team with Carvajal (or Nacho), Casemiro, Modric, Kroos, Isco and Benzema all playing in their positions would not be denaturalized, as opposed to the one in the Benabeu that was so concerned with stopping Alaba and Ribery that completely forgot the middle of the park.
And even in spite of all I said previously, it's a final and it's football. The most sensible and sanest thing is to expect the unexpected, and not take anything for granted.
