The Danish striker produced a match-winning brace for the Magpies in their thrilling 4-3 Carling Cup third round win at Nottingham Forest and feels has proven a point with his display.
"I came in up front and scored two goals, so it kind of proves a point that I'm ready if needed," he said.
"That was really my goal - to try to prove that I'm ready to play if they need me.
"A lot of people are saying, 'We need strikers, we need strikers', but I scored two and we scored two more from defenders afterwards, so we can score goals pretty much all over the pitch and we showed that.
"We probably should have done a wee bit better defensively, but that's down to us all from the front to the back."
