With all due respect, many domestic players will take a pass on us strictly due to the distance from the major population centers in which they and their family/friends generally reside. This is not remotely a new one for the club in terms of domestic recruitment hurdles.
Foreign players, like all others, will generally be looking at similar competing offers when considering clubs. If there isn't much between the offers financially, would your contention be that the distance/time we are from a proper international airport doesn't matter to foreign players considering offers from, let's say, us and someone like Watford/QPR/West Brom or within/near their own country?
Was this not also a point of contention in the possible hiring of Kim Hellberg, or at least one the media reported on?
I get that the rest matter, but I think it's often too easy to overlook how important things like proximity to one's family/friends is to players. Players these days often have more of a choice where they end up than they previously did and the unfortunate reality is that, for most players, Swansea isn't a place to which they're itching to move. Certainly there are always exceptions.
