Of the small amount of Leigh fans I follow on Twitter, I've seen the yin and the yang.
On one hand, the sensible ones that realise friendlies don't really mean a lot, and that the Wigan side was far from a full strength team, whereas Leigh's was only missing one or two players. Happy with the victory, optimistic, but not getting carried away.
On the other hand, I've seen at least one thinking it's a famous victory against one of the best sides in the country and it proves that Leigh are mighty and will destroy all this season.
Every club has the crazies, and every club has the sensibles. If we managed to pull off a fluke and beat Leeds on Sunday, I'd fully expect to see similar comments from some of our fans about how we're amazing and better than the champions.
