In the upcoming match Barcelona will also face Valencia as we know Valencia is in its worst performance meaning Barcelona can win easily.
Valencia is struggling to get out from the bottom three this can make them play more open to score goals, and even though Barcelona better compared to Valencia the recent defeat against Almeira should be a warning to them to be more careful when dealing with lower teams because they still have the ability to beat Barca, especially when playing against weak teams where Barca should be able to make their position even more save with take full points if they fail to do this then Madrid will benefit.
Normally, Barcelona will beat Valencia. Historically, although Valencia tend to play good games against big teams (only to then mess up against smaller teams), the Camp Nou is not usually a good place for them. If we add to that Barça's excellent season, coming off the back of beating Madrid in Copa del Rey at the Bernabeu, and Valencia's shitty season, bookmakers will pay almost nothing if you bet on Barcelona to win.
In fact, I just looked at Betfair and they're paying 1.42 for Barcelona to win, 7.5 for Valencia to win, and 4.6 for a draw.
Barcelona have no choice than to Valencia, if Barcelona miss this chance again to increase their point it can limit them from winning laliga this season. I Hope to see Barcelona win against Valencia without any struggle. Barcelona just need to try their best to achieve their targets for the season. Because of how winning laliga is important to Barcelona, they never took any league competition serious, and if Barcelona starts showing poor performance in laliga which have always been their target it will be too bad after all the good efforts.
