I don't think it's 'Nailed On' but there are some very obvious reasons why it could happen
A/ Club known to be admirers. We wanted him before we got Enzo, Southampton got in first as they were already relegated and we were still in with a chance of staying up
B/ He plays a very similar style to Enzo - We got promoted at first time of asking with that style, Martin also got Southampton promoted playing that style
C/ There is zero compensation for bringing him in
Saying there is 'not a chance' of it is complete nonsense.
