Write to them on some nice headed notepaper and set them on a course to a bidding war. It would be interesting to see Man Utd and Newcastle Utd bid for it.
There is an alternative too. Write to Roman Abramovich, the owner of Chelsea and one of the richest man on the planet (we're talking billions) and see how much he would bid in order to stop Man Utd getting it.
Dude offer it to him for £500,000 and watch your hand get snapped off.
