there's been plenty of right backs in england in the past 12 years or so, just none in Neville's league.
as long as his injuries haven't fcuked him up for good, then I have no doubt that he will be back in the England starting 11 as soon as he is match fit.
Richards can play on either left or right side and centre half also so, as I've already posted somewhere else, a good football manager would be more likely to drop Cole and move Richards over to the left to give Neville his place back at right back.
