It doesnt really matter does it, as long as real madrid could keep on getting 3 points then it doesnt matter. They were facing valencia instead of barcelona that faced espanyol. It is a good thing that they won with 1 goal rather than atletico that unexpectedly lost to a weak team like levante
and barcelona had easier opponent than real madrid. especially barcelona did not want to make that mistake again, because this is their hope to get the league trophy, after they were knocked out in the Champions League.
