He has only himself to blame. He wasted some good chances. What was he doing with a counter attack in the 1st half? Yildiz was wide open, while Dusan decided to dribble which he isnt good at. In the 2nd half, he spent more time on the ground, falling down at the slightest touch.
He just doesnt have good instincts for a striker, didnt pick on any cross. If he had more facets to his game, I wouldnt mind his lack of movement inside the box.
