"I think we can be. The more people we attract through the gates, the more money we generate and that means we give more to the manager.
"I have already decided to increase the playing budget for next season as a result because we are now just starting to plan ahead.
"Next season, I would think, we will be top four in terms of budgets so we will be pushing hard for the play-offs if not automatic promotion.
