Storm prop Tim Glasby charges into the Warriors defence in Round 3.

Storm prop Tim Glasby believes that while his side are happy starting the season undefeated, there's still plenty more for Melbourne to work on ahead of their Monday night clash with the Sharks.

Glasby was impressed by the resilience of the Melbourne defence during the Storm's 21-14 win over the Warriors on Sunday, but admits their attack is still yet to reach the level they expect. 

"To grind out a win like that and complete our sets and wait for them to make the mistake and hold on as long as we did, is a really good sign," Glasby said.

"Later on hopefully our attack will click a bit better and we can make life a bit easier on ourselves."

A field goal to Cooper Cronk in the 76th minute broke the deadlock and gave the Storm a lead with only minutes to go, before speedy winger Marika Koroibete picked up a loose ball and dashed home to seal the victory.

Glasby said that the experience of players like Cronk to assess certain situations and make the best decision available is invaluable during such tight games. 

"For them [Cam Smith and Cooper Cronk], that’s just part of their job and something they've been doing for a long time," Glasby said. 

"They take control there and they tell us where to go, and Cooper took the shot when he thought it was the right time and it was. It's really good to have that trust in those players to be able to make those decisions."

On a personal note for Glasby, the 26-year-old believes he's begun the season well, but like the Storm, said there's plenty of room for improvement over the coming weeks.

"Personally, I've been happy with it," Glasby said. 

"I'm just trying to do my job, coming off the bench into the middle there and adding a bit of spark if I can. I've been relatively happy but there's always something to work on, especially over the next few weeks."

The unbeaten Storm will come up against the Sharks on Monday night, and Glasby believes it will be another tough encounter. 

"I haven’t seen much of the Sharks this year but I know from playing them in the past they are a good, tough team and I’m sure they will be this week," Glasby said. 

"We've had some good grinding games with them in the past and it’s going to be a tough one in the forwards because they have some good really good players through there and have a bit of experience too."

A shining light for the Storm over the opening three rounds has been the performance of Kenny Bromwich, with the Kiwi scoring his second try of the season on the weekend.

Bromwich began the game in the centres and crossed over in the first half, and Glasby believes his early season success is a reward for his effort over the recent weeks, and joked he would love for his teammate to share the ball around a bit more. 

"Kenny is doing a great job, he's scored a couple of tries already, it would be good if he could share it with the other forwards but we will let him have it for now," Glasby quipped. 

"He’s going really well, he's playing great footy and his tries are just what he deserves."
