The match at Pittodrie was momentarily halted last night when a fan sprinted from the stands towards Hart for a selfie before scarpering back into the crowd.

The bizarre incident left both Hart and manager Ange Postecoglou baffled.

The Celtic boss explained: “I think we all were baffled. 

“It was like he had a free pass because he just wandered off and got back to his seat. 

“Fair play to him he’s obviously got some special pass that allows him to do that!”

But Postecoglou insisted he’s not a fan of fan incidents because of the unknown nature of intentions.

However, he conceded it was “harmless enough” at Pittodrie.

“I don’t like that because I always fear that you just don’t know what’s coming. 

“You don’t want players to react to that or get involved. At the end of the day it was harmless enough, overexuberance. 

“We were all a bit baffled by his entry and exit. He’s obviously got some all-access pass that none of us have!”
