Sharks coach Shane Flanagan has, for the first time, publicly declared Cronulla's interest in unwanted Bulldogs star Aaron Woods and says the club may make a play before the June 30 deadline.

Flanagan told Fairfax Media his Sharks had room in their salary cap to lure Woods this season and were in need of another front-rower.

The Cronulla pack had no answers to the South Sydney forwards, who all ran for more than 100 metres on Friday night.

Bizarrely, they lost prop Ava Seumanufagai at the start of the second half when he ran to the wrong end of the field for kick-off, only to come off for a concussion test and fail.
