Of course now it's in their favor even though I don't really like it, but the fact that they really excelled in the first leg cannot be eliminated and now they will play at Camp Nou with an aggregate of 1 goal, this is clear to be superior for them.
Now it only remains to see how Madrid will react after the defeat they have received again and again from Barcelona. It would be great if they started to wake up and at least be able to prevent Barcelona from bringing a trophy, but if not last season's situation is like the opposite this season.
The first leg of the Copa del Rey looked too monotonous and it seemed that only luck saved Barcelona from defeat. What is clear is that in the second leg, Real Madrid must have a mission to surpass this thin aggregate so that they can advance to the final round. But it doesn't look easy considering that Real Madrid have to go to Camp Nou to play the second leg, even so I'm still optimistic that Real Madrid will be able to beat Barcelona.
I believe that we shouldn't really be considering any wins that Barcelona has been any luck or anything. I feel like the best thing to do is consider that they are just too close to each other but looking at the league and even the league game result, Barcelona is a better team this year. Xavi has really turned this club around and the team is not like a full "team", its bunch of players put together, they are individually great but they are not even a team yet, and he will build into that slowly but even right now they look better.
So, any game they have do not look like that's a luck, it looks like we are talking about a better team and they can win the next game as well.
