With the Sharks denied five tries last weekend against the Manly Sea Eagles, Jeff Robson told the media on Wednesday that he and the side must capitalise on the opportunities they create against the Rabbitohs this Sunday.

With the Sharks earning no luck nor joy from the video referee last start, Robson said that the side must be better and leave nothing to chance when they square off with the defending premiers in the elimination final at the weekend.

"There was probably four or five opportunities that probably we might have scored in recent weeks. We were just that 10 or 15% off against Manly," Robson said.

"When you're that far off, you get over the line and you don't win games... everyone's looking forward to the finals series and the game against Souths."

Robson is one of the many Sharks with finals football experience, but he remains wary that the side's talents and premiership hopes extend beyond that of the veteran campaigners.

With young sensations Jack Bird and Valentine Holmes set to feature in their first NRL finals matches, Robson said that he and players like Paul Gallen, Michael Ennis and Luke Lewis will guide them through the season's biggest fixtures.

"They sort of take a little bit of a backseat, but Birdy (Jack Bird) has got a fairly old head on his shoulders," Robson added.

"He's not short on confidence, and he gets in there. If he wants the ball, he'll get it most times." 

'Robbo' discussed the imminent return of the Fifita brothers, and also fielded questions on his playing future beyond 2015.
