Perhaps after the game had ended, Twain would remember to explain to Anelka why he was the one replaced, and not Viduka or anyone else.
As the Forest team insisted on playing high balls on the field, Viduka was needed for his excellent headers. Being a sturdy and powerful center forward, Anelka was not suited for this task. Eighteen minutes into the game, most of Viduka's job was to support Anelka and wait for his opportunity to assist in the shooting.
Maybe in other competitions, Viduka's image was that he was there to assist Anelka, just like the relationship between a flower and leaves. Anelka was the flower and Viduka was the leaves. But in this game, when it was necessary to break open the Barcelona goal with high-altitude bombardment, Viduka became the flower and Anelka had inevitably become the green leaves.
