The gap between Barcelona and Real Madrid may widen further because Real Madrid is currently not in its best form. Mathematically, the gap between the two is only 6 points (if Real Madrid is able to beat Valencia in the postponed match), but if Valencia manages to steal points in that match, it is certain that Real Madrid will find it increasingly difficult to catch up with Barcelona.
Conceded 7 goals in two consecutive games is a step backwards for Real Madrid, their front line is also not as productive as last season, they seem confused when they get a chance. The problems faced by Real Madrid are very serious, Ancelotti must immediately resolve the problem to put pressure on Barcelona who are enjoying the pleasure of being at the top of the standings.
Valencia match wouldn't be coming now, it's going to be played sometime maybe next year, because Real Madrid will be playing against Osasuna and a Valencia is going to be playing against Español. As long as Champions League, Europa, and others are still in played, it will be pending but I'm sure that once they are done with them before the knockout stage, other matches that has been skipped, not only Valencia will all be played so they can balance everything.
I still don't understand Real Madrid at this point, Anceloti seems to be having courage about his boys but the more I look at them, they don't look good, the midfielders are not communicating with the forward, that's the main thing and I think they weren't prepared very well for the departure of Tony Kroos, nobody can do his playmaking like he has done for that club.
