El Clasico is arguably the most famous rivalry in club football history. Two of the greatest clubs in the football world will face each other on Sunday at the Camp Nou as Barcelona play host to Zinedine Zidane’s Real Madrid.

The Catalan giants have already clinched a domestic double this season, winning the La Liga, and Copa del Rey titles last week. On the other hand, a third consecutive UEFA Champions League final awaits Zinedine Zidane’s side. Notably, the last time these two sides met in La Liga, Barcelona destroyed Real Madrid 3-0 at the Santiago Bernabeu. On that note, here is a look at 5 reasons why Barcelona will beat Real Madrid in this Sunday’s El Clasico as well:

4Iniesta, Coutinho, and Dembele could exploit Real’s weakness on the flanks

The Galacticos are looking hugely susceptible on the flanks. With Dani Carvajal out injured, Real Madrid will be lacking a quality full-back on Sunday against Barcelona. Lucas Vázquez played as a right-back against Bayern Munich on Tuesday, but he struggled against the likes of Franck Ribery and David Alaba.

Though Marcelo is one of the best left-backs in the world, he has certain weaknesses. The Brazilian has often been caught high up the pitch this season and has left spaces open at the back on the left side.

Meanwhile, Ernesto Valverde has used Andres Iniesta, Philippe Coutinho, and Ousmane Dembele on the flanks this season. Given this is Iniesta’s last El Clasico, he could most likely go with Iniesta and Coutinho on Sunday, and both these players are more than capable of exploiting Real Madrid’s weakness on the flanks.
