The distance between first position and second position is indeed very far and impossible to catch easily. Therefore, the La Liga match may end quickly because it is already known who will be the winner, but this match will still be interesting when used to do gambling and make money from the results of bets in each match.
The remaining matches become even fewer and there's no chance happened in the standing as the gap between barcelona and real madrid remains the same. Any matches passed by barcelona with winning the game will be also decrease the chance of real madrid winning the trophy of la liga.
Barcelona become even closer to the trophy. It seems like that barcelona had a very big chance to take the trophy soon. 11 matches are remaining at this moment and real madrid had 12 points gap over barcelona.
Real madrid is still having 7 more matches to make sure that it will always be taking full points. Barcelona is still possible to go down again at the end of the season. Xavi is fully focusing to win la liga right now. This competition is very hard for real madrid as the club is in a bad position.
The next match gonna be another important match caused by the winning from the upcoming match will determine which club will take copa del rey for this season.
I would say that the final is here. The next match against a weak club should not be counted. Real madrid must have come with something different or it will lose against barcelona.
