Definitely a harsh call, however, Van Persie didn't hear the whistle? Pull the other one. The sound of the whistle is so high pitched, you'll hear it over the crowd. He took a chance and was punished in the extreme.
Now as for a joke, Bendtner! "I dreamed I would score the winner in the league cup final" - Missed the chance.
