FC Barcelona have had a perfect start to the current campaign, winning all five of their games in La Liga. They have scored 18 goals and conceded just four.
They are also formidable opposition at their home ground. Last season they dropped just two points at Camp Nou, and although Real Sociedad are UEFA Champions League quality opposition, it will be a huge ask for the club to leave the stadium with three points.
Brazilian forward Neymar is yet to find his scoring boots for Barcelona since signing in the summer, but has been creative, notching an assist in each of his last four matches.
Naturally, Lionel Messi is the real danger for Barca, with six goals and two assists in his four league appearances, but Real Sociedad have troublemakers of their own in Carlos Vela and Xabi Prieto, and have only lost two of their last 25 matches in La Liga.
Barcelona could find their sternest test of the season so far.
