MA substitutions seem to be influenced by yellow cards (and quite right too). There weren't any until Charlie Lee came on.
I think MA got the subs pretty good today. From early on in the second half it was always going to be a game where we had to grind out the win and the 11 were grinding it out pretty well. Lee came on to give us a bit more legs at the right time and more of foothold when it was getting to the crucial end period.
