Aston Villa boss backs Premier League
Martin O'Neill has backed proposals which could see his former club Celtic and Rangers becoming part of a revamped Barclays Premier League.
The league are due to discuss the possibility of extending to two divisions - including the two Scottish giants - during the summer.
And Aston Villa boss O'Neill believes the duo would become "monumental players" if they decide to move south of the border.
O'Neill said: "My personal thought is that Celtic and Rangers would enhance the Barclays Premier League.
"Glasgow is a phenomenal football city. Celtic house 60,000 fans and Rangers house 50,000 fans every game. I'm not sure about Rangers but I know Celtic's capacity could go from 60,000 to 80,000 overnight, without a doubt.
"When I was manager of Celtic a number of years ago, there was some talk of both teams joining the Premier League in some capacity.
"There was mention of them being put in the Championship too, or maybe even lower down than that, and then making them work their way up through promotion.
