Judging from the formation that Barcelona did with their 4-3-3, I think this will be an open game, but if you look at Sociedad, they are actually still quite good by placing 3 midfielders and 1 player as a second striker to support Kubo and Isak in attack.
Kick Off starts in a few minutes now, looks like it's going to be a pretty good thing to see and Barcelona have to win for sure.
The first minutes are spectacular. 2 goals in 5 minutes and Lewandowski 50 seconds after the start of the game. Aubameyang and Depay are not in the game and also Raphinha but Pedri (19 years), Balde (18 years) and gavi (18 years) are playing. Three very young players, when was the last time that happened at Barcelona?
