Barcelona played a 0-0 draw with Roya Vallecano in La Liga opener on Saturday evening encounter at Nou Camp.
The Catalan side coach Xavi focused on his starting line with Ousmane Dembele, Robert Lewandowski, Raphinha combination with Gavi, Pedri, and Busquets in midfield.
Barcelona dominated the match with almost 70 per cent of possession and 18 goal attempts to two for Rayo.
Rayo’s five-man defence did a superb job in shackling Lewandowski, who barely touched the ball the entire game.
Barca coach Xavi Hernandez tried to break the deadlock by sending on forwards Ansu Fati and Pierre-Emerick Aubameyang from the bench, but Rayo showed real grit to hold out for the draw.
