The Schalke striker revealed that there are many emotions going through his head and insisted he does not know if he will start on Sunday despite Van Marwijk's expected changesNetherlands striker Klaas-Jan Huntelaar has admitted that he is looking forward to Sunday's crunch match against Portugal.
The Oranje head into their final group match in a must-win situation after suffering two consecutive defeats in Poland and Ukraine.

"I am feeling nervous for the last match," he told reporters at a press conference. "I am feeling positive energy for the game, which will be our last chance.
"We have to score twice and I am convinced that the Germans can and will beat Denmark."

"One can always guess, but I do not know what changes he is going to make,"
