Barcelona and Real Madrid are seeking to break their ties and isolate themselves to the top of the Spanish league when the first is a guest of Real Sociedad tomorrow, while the second will be visited tomorrow, Valencia, within the 17th stage.

The "Alblograna" and "Al-Maringi" are equal in number of points, and each of them has 34 points, with an advantage for the first with a difference of goals, knowing that the "Classico" match will take place next Wednesday. Barcelona is entering its match with Real Sociedad (fourth with 27 points), after a difficult confrontation last Tuesday in San Siro, which ended with a 2-1 victory and the elimination of Inter Milan, the leaders of the Italian League from the Champions League, with a team made by the reserves. In contrast, Real Madrid's match against Belgian club Bruges in the European competition was not much easier despite winning 3-1. The royal aspires to return from Valencia with the three points, but his host (the eighth, 26 points) will not be up for grabs.
