Why is Casemiro often substituted after 60 minutes?

"Casemiro is often substituted after 60 minutes, is this to protect him from injury or is it tactical? He seems perplexed by the substitution, because he is more influential to the game than others. There are two elements to this and we are only going to find out whether the latter is correct over the next three games. First, Ruben Amorim is mindful Casemiro is 33 and his minutes need managing."

"After the Newcastle game, Amorim dismissed a suggestion he had taken Casemiro off to ensure he was fit for the Wolves game, stating he only dealt with what was in front of him. However, with seven senior players missing and doubts over Mason Mount, United cannot afford to risk losing any more. Casemiro might have been surprised to go off against Newcastle, but it would be much more of a surprise if he did not start against Wolves, or Leeds or Burnley after that."

Casemiro is frequently substituted around the 60-minute mark, raising questions about protection versus tactics. Ruben Amorim monitors Casemiro’s minutes because the player is 33 and requires careful load management. Amorim has praised Casemiro as an example for squad preparation and coping with match demands, indicating the player remains important. Amorim denied withdrawing him solely to preserve fitness for the next match, saying he responded to the immediate situation. With multiple senior absences and uncertainty over Mason Mount, conserving Casemiro for upcoming winnable games is likely to protect United’s Champions League qualification prospects.
