Three minutes into stoppage time in Wednesday's friendly, Gamst Pedersen cushioned a pass on his chest, let the ball bounce once and fired a looping shot over the Finnish keeper and into the net from 25 metres to seal a 3-2 win.
He then made taunting gestures towards the home supporters, who had booed him earlier in the match, and turned away from them pretending to pull down his shorts.
"I stand by what I've done," Gamst Pedersen told Norwegian tabloid VG on Thursday. "I just had to get it out." Gamst Pedersen, who plays for English Premier League club Blackburn Rovers, has struggled to find consistent form for the national team and has been on the receiving end of jeers from Norway fans before.
"I didn't play my best game, but I scored the decider anyway," he said.
