Real Madrid's Sergio Ramos to play through pain against Barcelona - report

Real Madrid captain Sergio Ramos is set to take a pain-killing injection to play against Barcelona and will undergo shoulder surgery after El Clasico, according to AS.

Ramos left the pitch in pain after falling heavily while scoring the opening goal in Madrid's 3-2 La Liga defeat at Sevilla on Sunday and underwent a scan on the injury on Tuesday morning.

He has already been ruled out of Spain's upcoming friendlies against England and Belgium and the centre-back was also a major doubt for the game against Barca on Nov. 21, but AS claims he will take a cortisone injection for that match and then undergo an operation.

Ramos had first dislocated his left shoulder during September's Champions League win over Shakhtar Donetsk, and has since played only in the club's key games.

However, he suggested to Canal Plus that his participation against the likes of Atletico Madrid, Paris Saint-Germain and Sevilla had been a mistake.

"The shoulder is not so good," Ramos said after the loss to Sevilla. "I fell supporting myself while scoring the goal. The important thing is to recover, and I'll have a scan on Tuesday. I have played four or five games recently with an injection.

"When you have a recurrence of the injury it is hard to take. I try to help the team, and now I see the risk, and the value in recovering completely."

There have been persistent reports in the Madrid media that members of the squad are unhappy with the club's medical department.

Ramos is one of a dozen Madrid first-team squad members to miss games through injury so far this season, with muscle injuries a particular issue given James Rodriguez, Gareth Bale, Karim Benzema, Luka Modric, Pepe, Keylor Navas and Mateo Kovacic have all suffered strains or tears in recent weeks.

Both AS and Marca claim Madrid's players are unhappy with how the club's medical team are dealing with this issue, and chief of medical services Jesus Olmo is said to be particularly unpopular with certain players.

Ramos said he would address the matter at a more appropriate time.

"Now isn't the best time to talk of medical matters," Ramos told Canal Plus. "We have to help each other out to be in the best possible shape at the end of the season. When the time comes to talk about our problems, those of us who are better placed to talk will talk."
