Parramatta coach Brad Arthur has lashed out at the referees for failing to use the bunker to examine two controversial Melbourne Storm tries on Saturday afternoon.

The Eels coach was dumbfounded by the decision of the match officials to award Melbourne two of their tries that were overshadowed in doubt.

When asked what was the difference between the two teams, Arthur said: "The bunker."

"We've got the bunker there, don't we, so we have to go to the bunker to look at the tries. Our first try went straight to the bunker.

I think they need to have a look at it. At least make sure .Why did we look at our first try? Why did we look at that?"
