DAVID MCCALLUM admits Rangers let themselves down collectively as they blew their chance of Hampden silverware against Hibernian.

New Ibrox boss Giovanni van Bronckhorst watched his side crash to a 3-1 defeat on Sunday as they missed out on an Old Firm final in the Premier Sports Cup.

A first half hat-trick from Martin Boyle ended the semi as a contest on a night where a Scott Arfield strike just before the break offered Rangers only a forlorn hope.

The champions were complicit in their own downfall as they produced another shoddy defensive showing and interim boss McCallum knows there can be no Hampden hangover as van Bronckhorst prepares to take charge at Ibrox.

"I think it is a we," McCallum said when asked if his players let themselves down at Hampden. "I think we let ourselves down today.

"We are part of the staff, we are involved in what has happened in the game. The players will be frustrated because we know that we should be managing these games better, I don’t think there is any question about that at all.

"They are honest enough to deal with that. I keep going back to the goals that we lose, you can’t leave yourself with a 3-0 deficit and find that it is going to be easy to come back into it.

"As a group we are frustrated, there is no question about that at all. But they are also a group that need to get back on and move forward again because there is a lot to play for this season.

"A massive game coming up on Thursday evening and after that we are back in league business. There is a lot still to be played for.

"Tonight is hugely disappointing but we have to look forward and make sure we bounce back in the next game."
