I would suggest the possibility that we seem to focus so heavily on one target at a time because it kind of makes sense to do that.
We'll try as hard as we can to get that number 1 target but if we really can't make it happen we move on to number 2, which has probably been having some prep work done on it quietly away from Twitter (again the difference between what fans know and what is actually happening is probably pretty big - especially when it comes to secondary targets).
In the end, although it didn't turn out great last season when we were trying to add 10+ players to the squad, we do always get some business done by the end of Summer windows.
This time I don't think it'll be as much as a disaster if we add a few players at the end of the window as the volume of players is much lower probably so it won't be as disruptive and the squad we have is good enough to integrate players slowly.
