Even though I'm hoping its Labbadia because he will bring fresh enthousiasm and ideas to the place, he would have to act fast in bringing in any players from Europe, before and if Brexit goes ahead. (PS I won't get started on that- not that the Mods would let me
But we would be faced with a panel having to approve new players, the sort of complication we absolutely don't need. I think they use as a rule of thumb based on number of international appearances? Mind you that would apply to all British clubs under which ever manager, but in the case of a European manager, he is likley to have alot of targets on the continent.
