First Barca goal should not have stood after foul on Xavi Prieto, second goal from penalty, no one picking up Juanmi for Sociedads first goal and Cillisen all over the place then Sociedad give ball away cheaply as Suarez scores from fast break, Barca defence sleeping for Sociedads second then Barca score two late goals as Sociedad chase the game. Not convincing and better team like PSG could really exploit Barca with players like Cavani, Di Maria and Matuidi on presses and fast breaks like we seen Celta and Athletic do. Yes Sociedad are no mugs and Barcelona will be happy to go through to the next round so job done but tougher tests lie ahead and we will see what this team are made of I have my concerns.
