Like I said, it doesn't work that way. At least it shouldn't.
Would be absolutely crazy if Woodward spent all summer chasing one target, then when that fell through, phoned Van Gaal to say "Vermaelen's not happening, anyone else you fancy?"
These things have to be worked on in parallel. Chase a number of targets for the position you've identified needs strengthening, all at the same time. If/when you make a breakthrough for someone at the top of your list, don't follow up any of the alternatives. If the number 1 goes elsewhere, you're not starting from scratch with alternates.
Who knows, though? With the cluster-feck we've seen these last two summers, perhaps Woodward hasn't grasped that himself?
