Los Blancos continued their 100% record to start the season with a convincing 4-1 victory away at Celta in a much-improved performance from last week against Almeria.
Karim Benzema opened the scoring with a penalty after 14 minutes, before Militao gave away a spot-kick shortly after. Former Liverpool attacker Iago Aspas converted the penalty before Luka Modric restored his team's advantage just before half-time.
Vinicius Junior and Federico Valverde both netted in the second half to complete an emphatic victory for the European champions who are now atop the La Liga standings.
However, following Militao conceding the penalty, many supporters were upset with his performance. The 24-year-old was brought back into the side after he and David Alaba were replaced by Antonio Rudiger and Nacho Fernandez for the clash against Almeria last week.
Militao has been a dependable performer under Carlo Ancelotti's reign at Real Madrid, but many now feel that new signing Antonio Rudiger should be their first choice. The German has arrived at the Bernabeu with high expectations after many excellent years at Chelsea.
After the full-time whistle on Saturday night, fans of the Galacticos took to Twitter to vent their frustrations at Militao following his poor display:
Carlo Ancelotti discusses Real Madrid's midfield options following Casemiro departure
Following Manchester United's announcement that they had reached an agreement in principle for Casemiro, Ancelotti was asked if a replacement would be coming to the Bernabeu.
Los Blancos have already signed Aurlien Tchouameni this summer for big money from Monaco. The Italian boss hinted that they have enough options for the new campaign. He told a press conference (as quoted by Madrid Universal):
“We have good and many players for that position. Like Tchouameni, one of the best midfielders on the market. Kroos can also play there and Camavinga.
“We have other players with other characteristics who can play. Tchouameni is more similar to Casemiro, but also Kroos can play there.
“Our midfielders now are Modrić, Kroos, Tchouameni, Valverde, Camavinga, and Ceballos. Six midfielders are enough for this season. They’re very very good.”
Casemiro has made 336 appearances for Madrid since his arrival in 2013 and was a key part of the side that won five Champions League titles.
