If the works syndicate won, I'd be on about £20m, so I'd make sure I had a season ticket again, and splash out for some box seats, etc. Not sure I would drop a lump sum in, maybe £1m with the proviso it doesn't get used stupidly.
If I won the full thing, I'd offer to redevelop Fir Park, starting with knocking down the South Stand and replacing with something sensible, removing the seating from the East Stand and installing that safe terracing stuff from Germany, and general bits and pieces around the place to make it a nicer place to watch a game, with facilities to bring other income into the club.
P.S. Part of any redevelopment would include a penthouse flat in one of the corners, with balcony for watching the matches.
