My comparison would be to Jack Butland who proved to be an extremely talented shot-stopper in the premier league, not quite good enough in terms of distribution (yet) to be signed by a top-half premier league team and now plays in the Championship. Butland is deemed too important to Stoke to sell and maybe Etheridge should be considered in that bracket as well.

Which clubs may be interested in him? In the Premier league I would suggest most clubs are settled with their first-choice keeper selection so will either be looking at him as a number 2 (potentially West Ham or Watford) or we're looking at a rival at the top of the championship. How much

How much should a chasing club have to pay? Depends on the chasing club and how much we can get out of them. If it is a club looking for a number 2 then perhaps Danny Ward becomes the comparison.
