Anthony Seibold has labelled Manly's Friday night loss to Brisbane as "disappointing" following their Round 9 defeat to the Titans, but is confident his side will bounce back.

The Sea Eagles were down 20-0 by half-time, with the Broncos eventually running out 32-6 winners in the Friday night affair, marking Manly's fourth loss of the season.

Speaking to media post-match, the senior coach admitted that he was disappointed his side couldn't challenge the ladder-leading Broncos.

โ€œIt is disappointing because we thought we'd come up here a give a really good account of ourselves, and challenge the team sitting at the top of the table,โ€ Seibold said.

โ€œWe just have got to keep working and keep building on the platform we'd made early in the season.

โ€œIt has been a disappointing two weeks but we will bounce back and keep chipping away.โ€

Manly were unable to put a stop to Selwyn Cobbo as he scored three tries throughout the 26-point win, while Tom Trbojevic was unable to have a big impact on his return from a groin injury.

Seibold dismissed talk around the fullback, conceding the team as a whole needed to do better.

โ€œIt wasn't so much of a comeback, he only had one week out but again we didn't give him enough opportunities down their end of the field, until the second half,โ€ Seibold said.

โ€œBut we probably got a little bit frustrated tonight, yeah... we put too much pressure on ourselves.โ€

Manly will next face the Sharks on Sunday, May 14 at 4 Pines Park.
