Real Madrid and Barcelona are having divided attention over their LaLiga and Champions League matches, and both teams are more focused on their Champions League match than they have on the LaLiga match.
And why should Barcelona be that focused on their Champions League match as much as Real?
They need to defend a 4-0 advantage, they could take it easily and focus on collecting 6 more pitns in La Lia while they have this breather, they meet Celta and Mallorca who might still compete for that 6th place and put some fight, while Madrid deals with Athetic who are eager to secure the 4th spot.
Barcelona has the advantage here, the crucial game is the one between them on the 11th, that's the one that matters, a win there over Real and the battle for the title is over.
One of Real Madrid's mistakes that made Real Madrid have to wait for Barcelona to lose points was when Barcelona drew against Betis, Real Madrid actually lost points when facing Valencia on matchday 30.
So that was their mistake and not getting trashed 4-0 by Barcelona on home ground?
Had they won that, they would be 2 points ahead now!
