I see. So in the circumstances you describe, not only will Villa pass up on getting £19m (let's say), you'll also voluntarily deprive yourselves of your best player. In other words, in your scenario you end up with no incoming money and no player either.
On a scale of 1 - 100, I'd give that possible outcome a zero .... which is one reason amongst several why all of the bargaining chips are NOT in Villa's hand, despite the many assertions on here to the contrary.
What bargaining chips are in Tottenhams hand?
It's closer to Arsenal?
