There was a loss for Xavi because he got 2 yellow cards against Atlhetico Madrid. This allowed Xavi to miss 3 matches. Against Las Palmas, Cadiz and Real Madrid. A disadvantage, because at the moment Barcelona is in improved form. They haven't lost after playing Villareal.
I actually think the same and the impact of the red car unfortunately will have a big impact on the pitch as next 3 games for Barcelona are not easy any longer. I can already see Real winning El Classico but also Las Palmas to score against them and with a bit of luck they can make a draw. This should also be a recovery chance for Atl.Madrid after they lost to Barcelona , they need to win next 3 games and hope Barcelona will stumble.
