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.
It's not only that Real Madrid can maintain its performance the same as last season, but because its rival team is also still not getting their best form and also the condition and situation of the Barcelona team this season has not improved. If a rival team like Bacelona fully returns to their best form and also gets a better situation and condition, then I believe Real Madrid will be difficult to be at their best this season but then again. If they only maintain their performance like last season, then no progress has been made, so the thing that makes Real Madrid still look strong this season is because the other teams are still in a difficult situation.
This can be seen at least from today's opponent Sevilla, if you also realize that Sevilla during the previous few seasons had even become a threat in the title race. But this season Sevilla is only in the standings which is not in a good position and with that, of course, Real Madrid's chance to win in this match is also very likely to happen.
