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.

The first thing that came to my mind when I looked at this picture is the Real Madrid - Barcelona final. Actually, another option is that on one side in the final there will be either Real Madrid or Liverpool, on the other side either Barcelona or Bayern. This is what I see at the moment, maybe some surprises await us, and Liverpool has already beaten Real Madrid in the group stage, and Barcelona's game doesn't always go well either.
