Two Turbo bursts were enough for Manly to scrap their way to a 14-6 victory over the Green Machine at Campbelltown Stadium on Sunday.

The Raiders had plenty of chances, but weren't good enough to take them against a desperate Sea Eagles outfit who were reduced to just 14 fit men for a large portion of the game.

But it will come at a cost for Manly, who lost the aforementioned Turbo - their star fullback Tom Trbojevic (hamstring) - as well as their five-eighth Dylan Walker (ankle).

It continued Manly coach Des Hasler's run against his Raiders counterpart Ricky Stuart - winning 17 of their 21 encounters.

While disappointed with his team's performance - but not their effort - Stuart was full of praise for a courageous Manly side that overcame plenty of adversity.

He's confident he'll be able to fix the Canberra attack that made their "job a lot harder than it should've been".

"The stats aren't lying there. We are struggling with attack and it's what I just told the players," Stuart said.

"We spoke quite thoroughly after the game. I can see what our issues are, but there's not a lot of time before next week's game. We've got to fix it quickly."

Stuart felt they tried too hard at times, with errors proving costly for the Raiders. They had five clear-cut chances, but were only able to take one of them.

Raiders five-eighth Jack Wighton produced a cracking cut-out pass for Elliott Whitehead to cross in the second half for their only try of the game.

They also had two big chances in the first stanza, with winger Jordan Rapana's usually safe hands eluding him after a Charnze Nicoll-Klokstad cut-out ball opened the door.

Raiders prop Emre Guler also went close from a nice short ball from hooker Josh Hodgson.

Then there were two moments of Jarrod Croker almost-brilliance as the Raiders pressed in the final 20 minutes.

Croker flew high for a George Williams kick, but just lost the ball as he went to ground it.

He then threw a wonderful flick pass for Rapana, but Manly second-rower-cum-centre Curtis Sironen produced a brilliant try-saving tackle to drag his foot into touch.

Stuart said they couldn't afford to give away possession like they did against a team like the Sea Eagles.

"We have set a standard that as a coach you want every week. It's not going to happen," he said.

"I'm not going to panic and change the whole shop around. We've just got to change a couple of little things and get back on track very quickly.

"But we're definitely not at the level of those two teams that played [Saturday] night [Sydney Roosters and Parramatta Eels] and we've got one of them next week.

"So we've got some work to do and we need to fix things immediately."

Manly on the other hand took both of their chances. And both came through Trbojevic. He went for scans on Sunday night, as did Walker.

It was a disastrous start for the Sea Eagles, losing Walker and centre Bradley Parker (concussion) inside the opening four minutes.

Things got even worse when Trbojevic limped off in the second half with another hamstring injury.

Manly will be left sweating on how many weeks he'll be out, having struggled with hamstrings in the past.

They finished the game with just one fit man on the bench, having spent most of the game with just two. But it just seemed to steel Manly, who were able to defend their way to victory.

Walker got his leg caught in an awkward position in an Whitehead tackle, which could put him out for a few weeks.

Manly coach Des Hasler said ex-Raider Lachlan Croker will likely take his place after a gutsy effort coming off the bench.

Parker hit his head on the ground after slipping into a Sia Soliola tackle, with the Raiders prop put on report - but he shouldn't have any concerns from the match review committee.

Before he went off, Trbojevic scored one try and set-up another.

The first came from Rapana's error - and three repeat sets - with the Sea Eagles fullback running over the top of Canberra centre Curtis Scott for the opening try of the game.

Trbojevic continued to terrorise Scott and drew him in before putting Manly winger Tevita Funa through the opening hole to make it 12-0 at half-time.

But that danger was lost just 12 minutes into the second half when Turbo limped off.

After Whitehead's try though, Manly winger Reuben Garrick's penalty goal was the only score despite the Raiders' chances.

Hasler said it was a win that would go down in Manly history.

"It's one of the best wins I've ever seen in a maroon-and-white jersey, particularly against a quality outfit like Canberra," he said.

"We lost one [player] in the third minute, one in the fourth minute, lost Turbo just after half-time.

"We had one of our back-rowers playing centre, a back-rower playing six, but they showed enough to hang in there. Wins like that help build seasons."
