But the visitors were left frustrated after squandering some good chances towards the end.Raul De Tomas struck the post twice either side of an effort from Landry Dimata, whose header from close range also came off the upright. The Blaugrana, though, would be happy to return to winning ways after five games. There were plenty of positives to draw from the match and perhaps a glimpse into the Barcelona future under Xavi too.With the narrow win, Barcelona moved above Rayo Vallecano to sixth place in the league table with 20 points from 13 games while Espanyol dropped to 11th.

That earned him a call-up to the senior team, and he delivered another electric performance.Gavi and Gonzalez were good, too, as the former Barcelona captain fielded eight La Masia graduates. That's likely an indication that he's going to lean a lot on homegrown talent going forward.
