Real Madrid and Barcelona have advanced to the knockout stages of the Copa del Rey with some suffering, after overthrowing Unionists and Ibiza respectively. So, they will be in the hype next Friday in the City of Soccer of Las Rozas (1:00 pm, through the official channels of the RFEF and on As.com) and, if chance wishes, they could face in the next round.In Friday’s draw there will be no hype of the Spanish Super Cup, as it did for the sixteenth. So that, there will be one of the First Division teams, another with the Second and, in case there is any classified, another with those of Second B. If the last conditioner is met, the rest of the third category of Spanish football would face each other with a First team, but this could be anyone, not necessarily a big one. So far, the four Supercup teams, exempt in the first two rounds, faced yes or yes to a Second B. It will be a condition that disappears from now on.LaLiga SmartBank teams will also play against a First Division. That does not mean that the LaLiga Santander face each other, since there will be more classified than the total sum between Second and Second B. In other words, Real Madrid or Barcelona can play with each other, against one of the same category or against one of lower division.Provisional draw bombsFirst division: Osasuna, Sevilla, Barcelona, Athletic, Real Madrid, Villarreal, Real Sociedad, Granada and Valencia.Second division: Zaragoza and Tenerife.Slopes: Ebro-Leganés; Mirandés-Celta; Badajoz-Eibar; Ray Vallecano-Betis; Cultural Leonesa-Atlético de Madrid.
