I was thinking bitton more for his ability to shoot from long range and occasionally completing a pass, besides I think Damian duff doesn't think keepers are needed in 5 a side, and well if having fullbacks prevents having even more wingers in the side then having a keeper who can shoot from range and pass the ball reasonably accurately might actually be an innovation in Scottish football that causes the other Scottish teams confusion and forced to play with no attack minded players at all to cope with the goalkeeper/attacking midfield play of the new system of fear.
I mean the only thing celtic keepers ever do is make crap passes and pick ball out the net on the only attack of the game from the other team.
