Top 5 central defender in the world (with a case to argue he's possibly the best). The maximum value for a central defender is £30m. I'd say he's worth £25-£30m. If United received a £30m bid, they wouldn't accept it, but it would bring them to the table.
Contracted till 2014, so United could get maximum value out of any transfer.
TransferMarkt's valuation.
A) IRA Bomber was joking. Of course United would take him.
B) The circumstances regarding VDV's transfer were very suspicious. His asking price literally dropped €10m overnight. Madrid wanted nearly €20m and all of sudden he was at Tottenham for like €8m or something. Very bizarre.
