Not sure that postponing is the right thing to do though, is it? I mean, clubs surely know the risk when they sign players from from a long distance away like South America. And in theory they should all have a decent number of players from England.
If we had no South American players and we were playing a team with two or three good ones who then might miss the game then I doubt we would have been best pleased if the Premier League waded in and postponed it.
