17' Los Blancos have been excellent to start the game and deserve their lead. Atletico have to respond here.
14' Vazquez has a run at Hermoso down the right flank and wins a corner off the legs of the defender.
13' Madrid have settled into a nice rhythm to start the contest and are putting the visitors under pressure at the back.
11' CHANCE! Benzema peels off Trippier at the back post to latch on to a cross from Vazquez, but he scuffs his effort wide of the left post.
10' SAVE! Benzema lines up a drive from the right inside channel and he hooks his effort towards goal with power on his left foot. Oblak barely has time to react, but the Atletico keeper does just enough to turn it on the post before it bounces clear.
8' The home side are enjoying the better of possession in the early stages, but Los Rojiblancos are disciplined in their shape.
6' WIDE! Herrera diverts an offload inadvertently towards Modric, who strikes first time towards goal. His effort travels across Oblak, but just wide of the left post.
3' Casemiro comes across to dispossess Trippier and takes a knock to the ankle in the process. Madrid get the free-kick, and fortunately the Brazilian is fine to continue.
2' Llorente surges down the right flank into space, but his cutback towards Felix in the box is cut out by Varane.
1' We're underway in the Madrid derby.
Atletico Madrid have failed to win in their last eight LaLiga games against Real Madrid (D5 L3), after winning four of the previous six against them in the competition (D2).
Atletico have also made one change to their line-up from their win over Salzburg. Saul drops out of the side on to the bench as Herrera gets the start in the middle of the park. Jose Gimenez is still missing with a thigh injury for Simeone's men.
Real Madrid have made one change to their side that beat Borussia Monchengladbach during the week. Rodrygo drops to the bench as Carvajal comes into the team at right-back. Vazquez, who was deployed at the back in the contest against Gladbach, pushes forward into the final third to support Benzema and Vinicius.
ATLETICO MADRID SUBS: Ivo Grbic, Geoffrey Kondogbia, Lucas Torreira, Saul Niguez, Angel Correa, Thomas Lemar, Renan Lodi, Ivan Saponjic, Vitolo, Sime Vrsaljko, Miguel San Roman.
ATLETICO MADRID (4-4-2): Jan Oblak; Kieran Trippier, Stefan Savic, Felipe, Mario Hermoso; Marcos Llorente, Hector Herrera, Koke, Yannick Carrasco; Luis Suarez, Joao Felix.
REAL MADRID SUBS: Eder Militao, Nacho Fernandez, Marco Asensio, Marcelo, Andriy Lunin, Federico Valverde, Alvaro Odriozola, Isco, Rodrygo Siva, Diego Altube.
REAL MADRID (4-3-3): Thibaut Courtois; Daniel Carvajal, Raphael Varane, Sergio Ramos, Ferland Mendy; Luka Modric, Casemiro, Toni Kroos; Lucas Vazquez, Karim Benzema, Vinicius Junior.
Atletico have enjoyed an outstanding start to the season, but can make their start seem even stronger with a win over Real Madrid tonight. Diego Simeone's men are unbeaten this term and have reeled off seven wins on the bounce in the league. They were solid during the week to ease past Red Bull Salzburg in the Champions League. Los Rojiblancos can make a statement for their title hopes with a victory over their bitter rivals.
Real Madrid begin the day six points adrift of Atletico at the top of the table. Zinedine Zidane's men already secured a vital win in the Champions League this week to secure a place in the knockout stage by defeating Borussia Monchengladbach. Los Blancos can now turn their attention to the deficit in LaLiga. They've not been at their best this term, but a win tonight could swing momentum in their favour.
Good evening and welcome to the live commentary of the LaLiga clash between Real Madrid and Atletico Madrid at the Alfredo Di Stefano.
