REFEREE Bobby Madden was forced to halt today's Premiership clash between Dundee and Rangers after kick-off following a crowd protest.

Ibrox supporters lobbed toilet paper onto the pitch as they continued to protest against the club's decision to take part in the Sydney Super Cup.

Reports have suggested that the game may be in serious doubt.

It's claimed "unresolved issues with the organiser" are ramping up behind the scenes after the plans for the friendly tournament were announced.

Rangers manager Giovanni van Bronckhorst respects the decision to play against Celtic in Australia was made in the club’s best interests.

A number of fans of both Glasgow clubs have reacted angrily to this week’s news that they will compete against each other in the Sydney Super Cup in November.

Some Rangers fans appear particularly agitated that the event has been billed in Australia as a homecoming for Celtic manager Ange Postecoglou.

Fans’ group Club 1872, the sixth largest shareholder in Rangers, this week wrote to the club seeking an explanation for the decision and claimed “alienating a significant portion of your supporter base cannot be seen as a sound commercial decision”.

When asked for his take on the decision, Van Bronckhorst said: “We know there is going to be a big gap during the World Cup and I know the club is looking for friendly games, not only in that window but also in the international windows we have.

“I think it’s an opportunity for the club to go there and play for the fans who are based in Australia. And of course the club made the decision to go there because they do everything in the best interests of the club.

“For me, I just need to respect that decision and play a good couple of friendlies in Australia in November.”
