In what was one of his and the Roosters' more impressive attacking performances of the year, Tedesco led the charge as Cronulla's five-game winning streak at PointsBet Stadium came to an end.

Craig Fitzgibbon's side have turned their home ground into a fortress this year, but they barely fired a shot until the second half against a Roosters side which has endured an uncharacteristically erratic run of form (7-5).

Tedesco was at the heart of everything that went right for the Roosters and his performance will hearten Blues coach Brad Fittler who is already without Tom Trbojevic and Latrell Mitchell.

The fullback's jinking runs helped get the Roosters out of the backfield and he was in the right place every time as back-up or support.

In all, Tedesco finished the match with 205 running metres, seven tackle-busts, two try-assists and a try of his own.

"He (Tedesco) worked hard during the week and it's intense as he's been," Roosters coach Trent Robinson said.

"He was saving tries on the end of the line and pushing through the ruck and it came out tonight. There was no backing off even though he's got a big six-week period, he was pretty impressive."

It helped the Roosters that the Sharks were way below par and in a worrying sign for Fitzgibbon, his side didn't score until the 56th minute when Ronaldo Mulitalo crossed.

"Any field position we got we gave away a penalty and they bowled us down field," Fitzgibbon said.

"I think our discipline was miles off and that was the response to not winning the simple parts of the game.

"We lacked confidence in each other (defensively), we've got to tackle stronger than that. We lacked the basic fundamentals in that area."

Fitzgibbon was coaching against Robinson for the first time since he left the Roosters at the end of last year. The Sharks mentor served as an assistant coach for Robinson for almost a decade but on Saturday the master won out over the apprentice.

Daniel Tupou put Robinson's side ahead with a double in the opening 20 minutes before a searing break from halfback Luke Keary.

Tedesco was backing up in support and flicked the ball out the back of his hand to send back-rower Nat Butcher over in the corner.

Tupou turned provider when he set up Tedesco on the inside, with the fullback calmly finishing to give the Roosters a 20-0 lead at halftime.

Veteran prop Jared Warea-Hargreaves pushed the Roosters further ahead when he crashed over after another incisive Tedesco break.

Wingers Mulitalo and Sione Katoa each jagged one back for the Sharks and when Cameron McInnes crossed to cut the Roosters' lead to 24-16 with 10 minutes to go, there was hope from the home fans that they could complete the comeback.

Roosters centre Joey Manu put paid to that when he wrapped up victory with a late runaway try before Connor Watson burrowed over to hammer home their advantage.
