O’Neill urges Celts to stay cool

CELTIC manager Martin O’Neill has urged his players to keep their cool in the white-hot atmosphere of the Old Firm derby at Ibrox. Referees have brandished 32 yellow and two red cards in the last six meetings between Celtic and Rangers.

And O'Neill, who was handed a two-game UEFA ban himself this week after a dismissal against Celta Vigo last week, has called for calm ahead of the Ibrox showdown.

O'Neill said: ''Discipline is very important and one thing I want to do is make sure everybody is on the field of play by the end of the game.
