Explained: Why Rodrygo and Thibaut Courtois were left out of Real Madrid squad for Clasico clash with Barcelona as Andriy Lunin gets the nod to start in goal by Carlo Ancelotti

The Brazilian winger sustained a thigh injury during Madrid’s Champions League clash against Borussia Dortmund earlier this week. Immediately after setting up Lucas Vazquez for the third, Rodrygo pulled a muscle and subsequent medical examinations revealed an injury in his right thigh.

Meanwhile, Courtois has been sidelined due to a recurring adductor injury. The Belgian initially suffered the injury during the La Liga match against Atlético Madrid, which ended in a 1-1 draw on September 29. After spending two weeks recovering, he returned to deliver standout performances against both Celta Vigo and Dortmund. However, his efforts in the recent game against Dortmund aggravated his adductor injury, forcing him back into recovery.

The statement on Rodrygo read: "Following the tests carried out today... he has been diagnosed with a muscle injury in the right femoral biceps."

On Courtois, the club announced: "Following tests carried out on our player Thibaut Courtois by Real Madrid's medical services, he has been diagnosed with an adductor injury in his left leg. Pending evolution."

Madrid’s squad depth and adaptability will be thoroughly examined with both teams battling for dominance. However, a victory would not only elevate Madrid to the top of La Liga but also enable them to equal Barcelona's La Liga record of 43 unbeaten matches, a feat achieved between 2017 and 2018.
