La Liga table toppers Real Madrid entertain Barcelona at the Santiago Bernabeu in the third instalment of El Clasico this season.
Los Blancos consolidated their position at the summit with a 3-0 victory at Mallorca last time out, stretching their winning run to five games in all competitions.
However, Carlo Ancelotti is sweating over the fitness of talisman Karim Benzema after the Frenchman went down injured last weekend and he will hope the forward is declared fit enough for the challenge of a resurgent Barcelona.
Here's how Los Blancos could line up.
1. Goalkeeper & defenders
Thibaut Courtois (GK) - The best goalkeeper in the world? He's making a compelling case for himself.
Dani Carvajal (RB) - The weak link in this Real Madrid backline and Ancelotti must get bodies across to support him.
Eder Militao (CB) - Has developed into one of the most commanding central defenders on the planet.
David Alaba (CB) - His pace will be vital in one-on-one battles with Pierre-Emerick Aubameyang.
Ferland Mendy (LB) - Ancelotti's preferred option at left back, giving license for Alaba to motor forward.
Casemiro (DM) - Relishes these battles with Barcelona and was sent off in last season's league meeting at the Bernabeu.
Toni Kroos (CM) - Has struggled with injury in recent weeks, although he played the full 90 minutes against Mallorca.
Luka Modric (CM) - Produced a midfield masterclass in the second half of the Champions League second leg victory over PSG.
Marco Asensio (RW) - The Spaniard is likely to be given the nod with Rodrygo an injury doubt.
Karim Benzema (ST) - Went down with an injury at Mallorca last weekend, but the Frenchman will be pushing to be involved this weekend.
Vinicius Junior (LW) - Four goal contributions in his last five outings for the Brazilian, which underlines his consistency this season.
