What is O'Neill's record at Ibrox?

Celtic's Martin O'Neill turns 74 on Sunday and to mark the occasion he is heading to Ibrox for the first time as a manager in 21 years. The Northern Irishman has already beaten Danny Rohl's side this season as Celtic defeated 10-man Rangers 3-1 in the League Cup semi-final at Hampden in November during his first interim spell. During his trophy-laden five-year spell in Glasgow, O'Neill led Celtic out for 11 Old Firm derbies at Ibrox, 10 in the top flight and one in the League Cup.
