Participation in the Premier League by some Scottish or Irish clubs has sometimes been discussed, but without result. The idea came closest to reality in 1998, when Wimbledon received Premier League approval to relocate to Dublin, Ireland, but the move was blocked by the Football Association of Ireland. Additionally, the media occasionally discusses the idea that Scotland's two biggest teams, Celtic and Rangers, should or will take part in the Premier League, but nothing has come of these discussions.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Why didn't they move to Dublin?
the move was blocked by the Football Association of Ireland.
