Real will definitely not have any problems at all. Barcelona had one bad game and lost against Real, which put the difference at 3 points, and they will want to keep that 3 point difference going if possible. This is why it is not going to be that hard for them to actually win this game, Sevilla is not doing good at all this year and Real is doing as well as we could hope for.
This is why it is going to be a decent game and Real will have another good win. They have built a team that goes against test of time, plenty of old players playing along side of many younger talent as well, I am expecting them to keep winning with this method for a long time, this year is still their year, they are still great like last year.
