No worries Jim. I could totally understand that point of view when people were taking it as gospel that Arsenal had manipulated that situation to make a 'concussion sub' to allow them to make a an extra defensive substitution, I just wanted to point out that wasn't the case.
But listen, I was watching that game shouting at my own players to get up and just actually play some feckin passes, so can totally understand everyone else's frustration.
Sometimes that's all it takes on the jaw. Like I said, I'm not going to judge the actual impact, just wanted to point out on this occasion that there seems there was some at least.
