Celtic skipper Neil Lennon revealed how he could have become the first Catholic player in the modern era to play for Rangers .

The former Northern Ireland midfielder was given a guided tour of Ibrox by then Rangers manager Jock Wallace in the early 1980s with a view to signing him. At that stage there was a tradition of the Light Blues not signing Catholic players.

And although Catholic John Spencer came through the youth ranks, it was the controversial and high-profile signing of former Celtic striker Mo Johnston by Graeme Souness in 1989 which effectively altered the club's position.
