The signings of Sam Tagataese and Jeff Robson may not be the end of the good news for long-suffering Cronulla fans with the NRL club hopeful of completing deals for Bryce Gibbs and Andrew Fifita this week.

The Sharks have tabled offers for the Wests Tigers props, and although the pair has yet to formally agree on a switch to Toyota Stadium, the club is anticipating news of their arrival before the weekend.

A Sharks official told AAP the deals could be done this week but said there were still issues to resolve before an official announcement.

New Zealand-born Tagataese, who can play at centre or in the backrow and started his career with Melbourne, joined the Sharks from Gold Coast on Tuesday and was named on an extended bench for Sunday's clash with Canterbury at ANZ Stadium.

Halfback Robson, who helped guide Parramatta to the 2009 grand final, will depart the Eels at the end of the season after agreeing terms on a two-year contract with the Sharks.

The acquisitions of Tagataese and Robson come hot on the heels of young stars Stewart Mills, Albert Kelly and Chad Townsend agreeing to extend their contracts in recent weeks.

The Sharks, who have lost front-rowers Luke Douglas and Kade Snowden to the Titans and Newcastle respectively, have also been linked with another Tigers player.

Utility back Mitch Brown is believed to be a target for the club he left last season.
