There's no weaknesses

Storm forward Bryan Norrie says Melbourne must bring their best on Sunday when they face a Sydney Roosters side with quality spread across the park.

The reigning premiers will travel to Melbourne to face Storm at AAMI Park on Sunday coming off the back of an impressive display in Round 12 where winger Daniel Tupou recorded a hat-trick.

"They have a great defensive pattern, they defend really well and have a great kick chase," said Norrie when asked about the Roosters.

"Their outside backs have some great footwork…and then they've got a big forward pack with plenty of representative stars.

"They've got a great side across the park, there's no weaknesses in their squad so we've got our work cut out this weekend."

Storm struggled in attack last week, not able to find a way through the Cowboys defence to score. Building pressure on the opposition and earning strong field position when in possession is an aspect of Melbourne's play that Norrie says will receive plenty of focus in the build up to Sunday's clash.

"Last week we were disappointed with our attack, losing Cooper Cronk is massive to any team and its massive to us because he's so vocal with what he's doing," said Norrie.

"We've done a lot of attack this week, hopefully we can improve from last week.

"We just try and simplify what we're doing and make sure there is a bit more talk and a bit more clarity so everybody knows what we're doing and we're on the same page."
