It's one of those things that every club's fans believes about their club. Like referees hate them, their manager has "no plan B", the club has "no ambition" etc. All commonly held beliefs by various clubs' fans unless your team is one of the big 6 or having a really good season. The other one is that teams always lose after the manager wins manager of the month.
Didn't our 8-0 win over Sunderland come off the back of an international break? I'm not 100% on that but I'm a good 85% or so.
