Nothing to do with Warrington but heres what I would do...
I have 2 major hobbies. 1 is collecting old books and the other is RL so I guess I could have the money to enjoy both to the highest level. On the RL side I would invest money into Leeds and be sort of a silent partner. I would like them to use the money to invest in quality players and to take Leeds back to the top of the league. I would also like to invest in other things like struggling clubs, youth and the international side of the game.
Oh and id pay Tony Smith whatever he wanted to come back to Leeds because my god he's good!!
