BRENDAN Rodgers believes players should be allowed to enjoy Old Firm goals but warned his Celtic team “not to cross the line” in any celebrations. Rodgers takes his team across the city to Ibrox on Saturday for the first Glasgow derby since April when a Rangers fan ran on to the field and tried to get to Celtic captain Scott Brown, while last week a Celtic supporter encroached on to the pitch and made a beeline for PSG's Kylian Mbappe.

Police Scotland will again address both dressing rooms ahead of the weekend’s game but Rodgers insists his players are already aware of their responsibilities.

He said: “I think it’s important to celebrate – but in the right way. I remember the Rangers boys got some criticism when they celebrated in the 1-1 game [at Celtic Park in March].

“Of course they should celebrate – they have scored a late goal in a big game away at their rivals. Milk it, that’s what you should do!

“That’s a part of it but you can’t cross the line. Go and celebrate with your fans, be with them, but always be sensible.

“In my experience up here the police have spoken to us before each game and I suspect it will be the same before this one. It’s just a reminder of our responsibilities. But I would remind the players of that anyway. These are pressure games but you have to stay calm.

“That bred the success of us in those games last season; our ability to stay calm and controlled under the pressure. I understand the feelings and the emotions in these games. You want them to be passionate, intense and aggressive. But it always has to be under control.

“Whatever frustration, anger or issues that you have – at the end of the day it’s still just a football game. Sport is competitive and intense but it should never spill over.”
