When one is busy explaining to, for example, a goal-shy boggle-eyed living-nicker that he is a useless reproductive organ it is perhaps understandably easy to miss seeing the captain pull up with a knacked calf just prior to being substituted.
You don't have to see him pulling up. You just had to engage for a millisecond and allow the most basic context clues to sink into your thick ****ing head. The second I saw Holding on the touchline my first thought was that there must be a defensive injury. And yet the first first thought of all of these fans was that Wenger had changed his mind at the last moment and opted for a defensive substitution, and then continued thinking this even AFTER they saw Kos coming off.
Yes, yes, I know. All I would say is that having a go at some pissed-up spectators whose wrath, however inarticulate and misdirected, could have been avoided by the team not playing like a bunch of complete cùntwarbles, seems to miss the key take-away* of the evenings entertainment, or lack of.
* My apologies for using this abomination.
When I attend football matches the fundamental narrative thread is always foremost in my mind.
I would not dream of such a thing my friend.
Perhaps the others you are mocking did not see Koscielny letting the bench know he wanted to come off, perhaps they thought JW could come on and we revert to a back 4 which we have done many times before, his introduction being to try and win the game.
Lot's of scenarios, all simply the view or opinion of other football supporters.
