Fonseca drops two of his best players - Rafael Leao and Theo Hernandez - supposedly bc they're not working hard enough. They go a goal up against Lazio, then, in the space of a few minutes, they're 2-1 down. He sends them on. Leao scores straight away and it's 2-2.
Is he a genius for the substitution? A fool for dropping them? Somewhere in between?
