Well an offer in the region of £4 per share would give him £16M.
If he personally wants £60M then he is looking for around £15 per share, and that offer would need to be made to everyone meaning that it would cost £15 * 11,500,000 or £173M for every share.
I would take it at £60 for the club which would make the offer at £5 per share. Still a tidy profit on his initial 400K investment
