Paolo di Canio felt Manchester City boss Pep Guardiola could've done more at Real Madrid.
City drew 1-1 in Madrid in the first-leg of their Champions League semifinal.
Di Canio said, "Real Madrid doesn't have players who can improve, some changes were made out of tiredness.
"But not City, on the bench they have the possibility of improvement, I'm thinking of Mahrez for Bernardo Silva who was playing badly. And you don't make any substitutions?
"I think then that people complain about how much you play in this football..."
