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.
