Rangers' convincing 3-0 victory over Celtic at Ibrox in the Premier Sports Cup quarter-final left the visitors' technical area in disarray. Martin O'Neill and Shaun Maloney could only watch as their team was outplayed from start to finish.

In his early months in charge, Derek Mc Innes finally delivered the marquee performance he had been searching for. Six players made their Old Firm debut from the start, but inexperience was no barrier as Rangers dominated every department.

Dan Neil starred with goals and leadership in midfield, while Olwethu Makhanya neutralised Celtic's Camilo Duran. Despite both sides entering the game in unconvincing form, Rangers displayed intensity and togetherness that overwhelmed Celtic, who struggled with basic ball work.

The result sets up an intriguing semi-final against Aberdeen, with Rangers now massive favourites. The performance also raises questions about the upcoming league title race, as Mc Innes appears to have found a winning formula.
