Well, both matches are important because they involve FC Barcelona and Real Madrid, of course, but they are indeed two games that are not very interesting to see taking into account their corresponding rivals.
Much more interesting, to me, will be the ones played by Betis, Athletic Bilbao, Osasuna and Real Sociedad, as their results could sentence their fate in the second half pf La Liga. But to each his own.
There is a point too, seeing Real Madrid and Barcelona, of course, La Liga will only be competition for these two. But look at Real Sociedad, Athletic Bilbao, Real Betis, Osasuna and don't forget Atletico Madrid, all of them have a narrow distance of just 1 to 2 points to shift each other's position in the top 4 standings.
That's right, but I didn't mention Atlético de Madrid on purpose because they won't play against the other teams I was talking about. These five teams, and a few more, compete for the medium to high positions, and the competition is fierce sometimes, and this is what I expect for this weekend.
