The violence at Sunday's Old Firm match at Ibrox was "completely unacceptable", a senior police officer has said. A Celtic physiotherapist was hit on the head by a glass bottle and glass was removed from the Celtic penalty area. Assistant Chief Constable Mark Williams said enquiries were continuing into both incidents during the game.

Rangers have not played at Ibrox since May 14, when, coincidentally, they beat Dundee 5-2 in a Premiership game and Clement is relishing the prospect of getting back to normal for the quarter-final tie against the Taysiders, albeit the Copland Stand will only be partially opened. The Belgian boss said: "To be honest, it's a buzz.

The men, aged 18, 22 and 25, were arrested after officers were called around 02:45 on Sunday after a large group was seen at the stadium and different areas were vandalised. Three other arrests were made for breach of the peace and drugs offences. Police Scotland also said 70 people were refused entry to Ibrox and 21 were ejected from the stadium.
