I am not too worried about the keeper situation. We have 3 Premier League keepers in the under 21 squad, along with a 4th currently playing for the under 23 at Watford, signed from Celtic I think, Scottish/ Italian decent? Surely the odds are good for one of these guys to make a breakthrough.
McCrorie at Rangers looked good in the old firm and certainly has the stature of a top goal keeper, though badly needs game IMO.
