The Sea Eagles' season is hanging by a faltering thread after a devastating second-half collapse against the Melbourne Storm in Perth on Saturday.

Manly looked firmly in control early, racing to a 14-0 lead and appearing poised to make the most of their opportunity against a Storm side fighting for their own season.

The Sea Eagles were able to capitalise on a one-man advantage after a sin bin; however, they headed into the halftime sheds just ahead at 14-12.

From there, the contest unravelled.

The Storm ran riot in the second half to secure a 42-20 victory, with Manly's performance falling apart when the pressure was at its highest.

The Sea Eagles completed just 57.9 per cent of their sets after the break, while they missed 18 tackles in the second half alone, twice as many as Melbourne.

Eight errors compounded their struggles as the Storm turned a two-point halftime deficit into a commanding victory.

Manly coach Kieran Foran was left deeply disappointed by his side's inability to maintain control after building such a significant early lead.

“I'm very disappointed in that performance. I just don't feel that there's a real hard edge about our footy at the moment,” he said.

“You should be able to put the foot on the throat and maintain a level of control, and it just looks as though we completely lost it.

“I feel very, very sorry for our fans and we had a lot to play for today. There was a lot on the line. There was good reason to turn up and put in a really good performance, and after about the half an hour mark that just wasn't good enough.”

Foran questioned the identity of his side following a defeat that could prove decisive in their bid to reach the finals.

“That's not the sort of footy team we want to be, and we've got to work out what we stand for because that's just way off,” he said.

Manly captain Jake Trbojevic echoed his coach's frustration, admitting the manner of the defeat was particularly difficult to accept given what was at stake.

“I think that's the most disappointing thing; we turned up here with everything to play for off a bye and to put in a performance like that, it's pretty hard to take,” Trbojevic said.

While the result has left Manly's finals hopes hanging by a thread, it has breathed life into Melbourne's campaign.

The Storm sit 11th on the ladder, two points behind Manly, and still hold hope of forcing their way into the finals despite their difficult position.

Saturday's comeback was particularly significant given Melbourne will have a bye next week, allowing them to bank the two competition points and watch the teams around them fight it out.

Craig Bellamy, who recently confirmed he will remain coach in 2027, refused to concede the Storm's season, instead urging his side to focus on the football in front of them rather than the increasingly complicated finals equation.

“We're certainly not giving up, but whether we can make it (the finals), at the end of the day we just take it out of the picture, and we just need to prepare well and play well and then see what happens from there,” Bellamy said.

Manly's pace to the top eight also remains mathematically possible, but would require results above them to fall in an exact sequence.

Manly will now return home to Brookvale Oval next week, where they face the fifth-placed Dolphins in what looms as another must-win encounter if their already slim finals hopes are to remain alive.
