The thing that gobsmacked me was making a triple substitution when you're 2-1 up, but a man down.
Given you made a sub at half time, you were still allowed three breaks in play, so surely you make three individual substitutions in order to run the clock down?
As far as the game itself was concerned, folk around me were berating Murray's tactics due to us not putting the game to bed, but I thought his shape and tactics were spot on - they weren't the reasons we failed to convert more of the many decent chances we created, nor the reason for the defensive calamities which so very nearly cost us.
