"We're a team with a lot of growth to do yet, a team with a lot of improvement," McClennan said. "There were many, many things we could have done better against Manly."
While he expected the team's attacking structure to improve with time, McClennan was most concerned about a defence that struggled to contain Manly in the opening 20 minutes of Sunday's 26-20 defeat.
"Defensively we got caught out a few times as well and we were a bit disappointed in that because we did a lot of work in the pre-season," he said. "All in all, after reviewing the match there's so much improvement in us that we have to strive for."
Much of the focus this week will be on eliminating ball-handling errors, particularly early in tackle counts. After coughing up five errors against the Sea Eagles, wing Manu Vatuvei will be under scrutiny, as will fullback Kevin Locke, whose mixed outing included a try, a try-saving tackle, a spilled bomb and being tackled over the sideline on a kick return.
There was some partial relief on the injury front yesterday, with an MRI revealing Ropati's injury wasn't as bad as first feared. Initial assessments put the recovery period at up to eight weeks, however that has been downgraded to three or four.
After sitting out round one with a knee injury, Jarryd Hayne is expected to return for the Eels although coach Stephen Kearney said it wasn't certain.
"The likelihood is he'll be back but he only ran on a treadmill last week," Kearney said. "It's a matter of how he pulls up after running and twisting himself over the next week. Obviously I'd like him to be in the side."
