Let's have a look...

I see a
Real Madrid - Liverpool semi final draw already there.

Nobody to stop Liverpool until then. PSG destroyed Brest but we are talking about Liverpool here. PSG aren't strong enough to eliminate them surprisingly.
On the other side, I believe the semi final matchup would be
Barcelona - Inter. It would be such a tough one to predict. I don't want to underestimate Inter. I assume Barcelona would make it by close margin then.
And an El Clasico in the finale... This is my prediction for now.

When I looked at the table for some reason I eliminated Inter directly, of course Inter will be the favorite in the Feynoord match, what will happen afterwards is very difficult. There is a high probability that we will see El-Clasico in the final, such a Champions League final would be really enjoyable.
Liverpool can be an obstacle for Real Madrid. I think Barcelona will advance to the final more easily, of course this is the Champions League, you never know what will happen, never know which team will eliminate which team.
