The Copa del Rey quarter-finals will feature an el Derbi Madrileño, so who will claim capital city bragging rights, and a spot in the last four?
Back in September, Real Madrid won 2-1 at Cívitas Metropolitano, with Rodrygo and then Federico Valverde the scorers that night.
Overall, Carlo Ancelotti’s team are ten points better off than their city rivals, despite having played a game less.
On Sunday night, los Blancos remained three points adrift leaders Barcelona by beating Athletic 2-0 at San Mamés; Karim Benzema and Toni Kroos both bagging spectacular strikes.
A week ago, Real Madrid almost exited this competition, staging a remarkable fightback at Estadio de la Cerámica.
They were 2-0 down at half time against Villarreal, only for second half goals from Vinícius Júnior, Éder Militão and Dani Ceballos to keep their Copa dreams alive.
Remarkably, los Merengues haven’t won this trophy since 2014, when Gareth Bale scored that goal against Barça.
So, will the 19-times winners move on step closer to changing that?
As for Atlético Madrid, this season has been pretty catastrophic so far.
They finished bottom of their Champions League group and have already lost five league games.
On Saturday, goals from Álvaro Morata, Antoine Griezmann and Mario Hermoso saw them swat aside Real Valladolid, with this just Atleti’s second win in seven.
So, with no European football to come in the spring, Diego Simeone’s side are going all out in this tournament.
Los Colchoneros have already eliminated Almazán, Arenteiro, Real Oviedo and Levante, but would not have been pleased watching the draw last Friday.
Simeone’s reign as Atleti boss took off by lifting this trophy in 2013, defeating Real Madrid at the Bernabéu in that season’s final.
A decade on, Real Madrid are big favourites to book their place in the semi-finals.
