I'm not saying a binding anything, VirginiaSpur. Madrid just makes the most sense as we saw this summer. They're not a direct competitor, rich as fuck, prone to irrational purchasing, and Bale seems interested in moving there. They have the best left-sided attacking player in the world, and if/when he leaves, he'll probably leave for a shit-ton of money to PSG or some other such money-minting monstrosity. I wager Levy would happily take just about all of Madrid's 50-60m transfer fee to allow Bale to fill the Ronaldo-shaped hole in their lineup.
If the landscape changes between now and then, Levy will no doubt adapt, as he always does. But as things stand now this makes the most sense to me in terms of our "end game" for Bale.
