THOUSANDS of football fans have descended on Parkhead for the Old Firm game.

Both Rangers and Celtic fans were in a jubilant mood ahead of the battle of the season.

As previously reported by the Evening Times, fans have been warned to behave themselves ahead of the showdown.

Superintendent Simon Jeacocke told the Evening Times: “There’s always a real sense of anticipation for these matches. It is something that we look forward to, but there’s going to be a significant policing operation in place.

"As a result, we’ve called in specialist resources from all around the country, so we’ve got public order, trained officers, mounted officers and dog branch officers available to me, as well as conventional police officers that will be working at this game.”

It was already announced that Rangers fans would be held inside the stadium for around 15 minutes after the final whistle.
