Not being funny like but, if we can't sell all our tickets, then it would come as no suprise that some 'reds' would get hold of tickets to go and watch a game of football.
Same as when I went to OT to watch a Champions League game. Me and a mate went to one game because they couldn't sell all their tickets, so we got some because he was over anyway, and being footy fans we thought "why not". Another game was the game against Real Madrid where the REAL Ronaldo scored a hatrick. It must have been the most sought after game in years, but we got a ticket (puts a sh!tter on the myth that Utd fans can't get ticket, I'm a die-hard blue and still got tickets at face value!).
Blues at OT, Reds at COMs, doesn't make too much of a difference, as footy fans, you'll got if you want to see a particular game or if you just want to watch some footy.
