Real Madrid are sweating on the fitness of Karim Benzema, Rodrygo and Ferland Mendy five days ahead of El Clasico.
All three players went off hurt during their 3-0 win at Mallorca on Monday.
Vinicius Junior put Los Blancos, before Benzema continued in his rich vein of form with a brace to settle the game.
The result kept Madrid top of LaLiga with 66 points, 10 points clear of their nearest rivals Sevilla.
However, there are now concerns about the availability of Benzema, Rodrygo and Mendy for Sunday’s showpiece clash with Barcelona at the Bernabeu.
Rodrygo had to be helped off the field by medical staff in the 71st minute after a challenge by Mallorca defender Antonio Raillo. Nine minutes later, Mendy was taken off with an apparent muscular injury, before Benzema was withdrawn with a calf problem.
“We have to evaluate them in the next few days. They don’t seem serious. Rodrygo’s [injury] looks like a knock, it bothered him a lot. Ferland has an abductor strain, and Karim didn’t feel good after jumping [for the ball].
“We’ll have to wait until Wednesday to see if they can recover for Sunday. Right now we can’t say anything. Let’s hope they aren’t serious,” Madrid coach, Carlo Ancelotti, told reporters.
