Melbourne Storm players celebrate their first-half try on Saturday night.

Melbourne are preparing for an unpredictable Brisbane team when the two sides lock horns at Suncorp Stadium on Friday night.

The Storm will be looking to make it seven straight wins over the Broncos. 

But the news this week that Wayne Bennett will resume the reins at Red Hill at the end of the year may have thrown a spanner in the works. 

Current coach Anthony Griffin has committed to staying on as coach until the end of the season, making for an interest dynamic in Brisbane as the club pushes to secure a finals berth.

Melbourne is another club vying for a shot at September football and its coach Craig Bellamy admits the announcement of Bennett's signing this week was the biggest surprise to him.

"That is probably the most surprising part of it, the timing of the announcement," said Bellamy. 

"The people who run the show up at the Broncos thought it was what they needed to do and they've done it.

"You have got to feel for Anthony Griffin, he has done a pretty good job this year.

"It is disappointing for him but he has handled it with a great deal of class. He described it as business, that is the way he is I suppose and I think he is right."

The veteran Storm coach called on his players to keep their minds on the job but did concede the mindset of the Broncos would be a difficult one to read.

"It could fire them right up, or they could be flat," Bellamy said.  

"At the end of the day I can't control that, I can only control how we prepare this week and make sure I do my job the best I can.

"Make sure my players are along that line as well… that is out of our control, how they turn up. We have just to make sure we turn up in the frame of mind like the way we have done the last couple of weeks."

The Storm will be coming off a five-day break and sit precariously in eighth spot on the NRL ladder.

This week begins a run of three consecutive away games with matches against the sixth-placed Broncos and ninth-placed Wests Tigers making for an intriguing fortnight for the Victorian side.
