I always find it a bit small time when someone declares they are going to buy something?
Just do it FFS, why publicise your interest to potential rivals, unless you don't have the money or need to apply pressure because you don't want to spend the necessary?
Same reason he went public with a late Chelsea bid, perhaps to give the Glazers food for thought?
He has the net worth to take it off the table before anyone saw it coming, which suggests he's either in it for the publicity or isn't as liquid.
Always makes me laugh when some hard man says they are going to kill someone the next time they see them...
