#ASKGUILLEM: Balague answers your questions on Sunday's Clasico clash

Barcelona travel to the Santiago Bernabeu on Sunday with the chance to extend their lead to five points over Real Madrid. 

Two weeks ago, when they travelled to Real Betis, Barça were six points back from Madrid. But they won in Seville and a lot has changed since. 

Zinedine Zidane's side were held at home to Celta Vigo and beaten last weekend at Levante. In the meantime, Barça have seen off Getafe and Eibar at home to leapfrog Los Blanos in La Liga. 

Both teams were involved in Champions League football in midweek, too, with Madrid's poor league form extending into Europe as they were beaten 2-1 at home by Manchester City. 

Barça left Napoli with a 1-1 draw the night before, despite not being at their best. 

Several players will miss this weekend's game through injury. Madrid are without Eden Hazard and Marco Asensio -- while Rodrygo Goes is suspended -- and Quique Setien is missing Luis Suarez, Ousmane Dembele, Jordi Alba and Sergi Roberto. 

To look ahead to the game, SPORT columnist Guillem Balague has fielded your questions on the fixture. Check out the video above.
