Barcelona shared the points in the first match. Barcelona should get full points against weaker teams from the start if they want to win the title. If not, Barcelona will be far behind in the fight for the title. Barcelona needs to get full points against Real Sociedad by any means. Otherwise, Barcelona will be 4-5 points behind Real Madrid.
Geez, it is the second fixture and the end of the league is way far ahead. There isn't any urgency for Barcelona to win or nothing in this match, it is better for them to adapt with all of their current players and strategy. With that cause, all the players will be getting used, and a consistency will surely come. That will be good since it will offer stability within all of their next matches.
