Real Madrid manager Santiago Solari discussed why he did not bring Isco off the bench against Rayo Vallecano on Saturday.
Solari used all three permitted substitutes during Los Blancos' 1-0 win at the Santiago Bernabeu and explained his decision-making after the game, per Ruben Jimenez at Marca:
"My interest is in ensuring that all players are well, happy and committed and we all work for that. I try not to make mistakes in the formation or the substitutions and I do that because it is part of my job.
