Rovers take on their local rivals on the Saturday afternoon of the event at St James’ Park, and Mantellato feels the outcome of the game is crucial.
“It’s probably one of the most defining games of our season so far,” he said.
“Being in a 23-round competition, you don’t have those games towards the end of the season where you can pick up a few wins.
“We’re sitting outside the top eight at the moment. We really need to make our run now into the month of June where we have mainly home games to provide a good catalyst to start our run now.”
This will be Mantellato’s first taste of Magic Weekend, and he admits that he unsure about exactly what to expect.
“All the players that have played in the Magic Weekend before have talked about the importance of the derby and how good Magic Weekend is,” he said.
“Those two occasions on the same weekend should make for a pretty big event.
“To be able to watch a game before you play and even watch a game after you play is something different as well. It’ll be a new experience. I’m going into it with the mind-set that I don’t know what to expect.”
