Perugia, Olivieri controversial: "the referee whistled first"

Olivieri very controversial after the play off match of his Perugia. These are the words of him to tuttob.com.

“It was a very intense match against a strong team that will surely fight for the victory in the playoffs. Let's say that when we scored that goal in the 90 ', then canceled, the referee whistled first to wash his hands. Seeing him again after the game, we all couldn't understand what he had whistled and we still can't explain it, too bad because there were two minutes left. "
