Melbourne Storm Coach Craig Bellamy is under no illusions his side needs to make improvements prior to this weekend's meeting with 16th placed Cronulla.

After a month of consistent football, Melbourne fell to a late comeback from the Knights in Newcastle last weekend leaving Bellamy's side in seventh position on the NRL ladder.

"We've looked at what we did on Saturday night and where we need to be a whole heap better," Bellamy said.

"We need to get back to having the attitude...but also producing the actions of what we did the four weeks before.

"Why we had a bit of a relapse there I'm not quite sure but we need to fix it up this week."

The Sharks will welcome back captain and talisman Paul Gallen this weekend after a virus stopped the from making the trip to New Zealand in Round 22. Bellamy acknowledged the influence the New South Wales skipper has on the Cronulla outfit.

"They've had a horrific run through injuries, that's really unfortunate for them," Bellamy said.

"Getting Gallen back is a huge plus for them, you've got to admire the way they played last week against the Warriors. 

"Especially defensively they were outstanding.

"We just need to get on with what we need to do, we obviously know what to do, we did it for a month."
