The Athletic are reporting that, Real Madrid had him signed and sealed for this transfer window for 50 million pounds (including add ons), but United, Barca, Arsenal and Spurs all kept in contact. Real pulled out at the beginning of August due to lack of cash. VdB decided where to go instead after speaking to Ole directly who impressed him. Also helped by VdS, Blind and Bergkamp, but mainly down to Ole. Also according to the article you got him for 40 million pounds including add ons, so 10M cheaper than Real had already agreed.
