Barcelona will do everything they can against Valencia, and I believe they will prevail. Barcelona needs to drop fewer points to win the title this year. They've already dropped two points. The Spanish league will be in full swing. This year, the race will continue alongside Real Madrid. We all know Valencia is a dangerous team. It must be difficult for Barcelona to suffer a surprise drop. If they don't want this to happen again, they absolutely must win this match.
Without a doubt this is a must win game and a clear winning for Barcelona because if you look at their head too head record against this Valencia team in their past five meetings, you will see that Barcelona has the upper hand and they have won four out of five, and they drew once, so in this game that Barcelona are still playing at home, it's like a mountain hills Valencia have to climb to get the three point or even a draw, though in the game of football anything can happen, but I will be betting on Barcelona to win this one here convincingly because they can't afford to lose any point at this beginning stage of the season now that real madrid are busy ranking up points just as you have already said.
