DB stated in 2017, that Leigh made a profit from smaller attendances. Obviously the matchday costs have gone up with the entertainment put on, and the chances are Leigh are close to the salary cap (even with a small squad) and probably paying for 2 marquee players.
Revenue is up on attendances and sponsorship, but DB is still very much bankrolling the club. Apparently the club are missing out on online merchandising sales with the website down for 9 months and stocks low at the shop. People seem to like anything spotted (who would have thought).
Last year was the key and that is where Derek bank-rolled the club with no guarantees, players like Asiata, Lam, Amone, Ipape and O'Donnell are the bedrock of this team and they all Championship rugby last season. This group are now stars of the Super League, but it was far from obvious that this would be the case.
I am guessing money is not an issue to Derek when things are going well, and things are going exceptionally well.
