VINE: Barcelona have given us a preview of the stunning mosaic that the crowd will unveil at El Clasico

Art and football crowds are not traditionally two things you'd put together.

But clubs are really starting to take advantage of their supporters' presence by getting them to produce tifos ahead of kick-off to motivate the players. Just last night we saw Borussia Dortmund fans create a gorgeous tribute to their team's 1997 Champions League triumph and while it may not have inspired the players to qualification for the  quarter-finals, it was certainly a stunning spectacle. And Barcelona have followed suit as the Catalan club have today revealed the mosaic that the Camp Nou faithful will unveil ahead of kick-off in this Sunday's El Clasico. That means there are now two guarantees for the clash with Real Madrid - 1. The Barcelona players will have goosebumps and 2. Sergio Ramos is going to get sent off.
