Real Madrid and Barcelona have a big chance of qualifying for the final.
There is definitely a potential El Clasico in the finale there. I'm saying this even though how much I know Liverpool are playing better than Real Madrid in general.

Because there is really something different with Real Madrid as for the CL. They managed to win this trophy even in their bad shape last season. They can push for it again now also.
On the other side, we might see a face-to-face between Barcelona and Inter. I respect Inzaghi's football but this is Barcelona's best season in the CL lately. I don't think they would mess up. They should be able to qualify for the final.
Although Real Madrid always has a chance to reach the final, but still, surprise results may occur in certain phases. And in fact, for the match against Atletico later I personally believe Atletico also has a chance to be able to beat Real Madrid. After all, in football basically it can happen, but when it comes to Real Madrid it is difficult, especially when it comes to the Champion League. But even so, Real Madrid is also a soccer team just like any other team, the difference is that Real Madrid has a very big winning mentality, so it will be a real challenge for every team that plays against Real Madrid in the Champions League.
