Barca are out of first place for the first time since the end of the 2012 season and now face a quick turnaround against La Real. Gerardo Martino will be hoping for a positive response from his side after their lackluster performance against Valencia that saw them not only drop out of first but end a 25-game home winning streak.
Real Sociedad will attempt to keep the tie close with the second leg back at Anoeta Stadium. Leaving Camp Nou win a victory would be a huge boost as they attempt to make their first final since 1988 (a match they lose 1-0 to Barcelona). If they can pull it off, it would be the first win by La Real at the Camp Nou since the 1990/91 season.
