Sharks star Siosifa Talakai has shocked NRL fans by giving his Eels opponents the middle finger during their shock loss on Sunday.

Cronulla knew a victory would take them into the top four with just one game remaining of the regular season.

And as the game was slipping away from the Sharks in the second half, Talakai showed his frustration by making the X-rated gesture to the Eels.

Speaking on Kayo Sports, NRL legend Matty Johns highlighted the moment, much to the amusement of the live audience who roared with laughter.

Johns said: “Siosifa Talakai took the opportunity to give the opponent the bird. Look at this.”

But he was not the only one to spot it as fans on social media were quick to react.

One said: “This is brilliant.”

While another reacted: “It’s funnier because they lost.”

And a third replied: “Talakai — what a man.”

But Talakai was not the only member of the Sharks to lose his temper during the humbling loss to the Eels.

Coach Craig Fitzgibbon’s anger boiled over as he was spotted smashing up his monitor.

Sharks star Tom Hazelton was sin binned for a hip drop to all but end their hopes of a late comeback.

The cameras then cut to Fitzgibbon who exploded, sending the screen crashing onto the table with a vicious punch.

The Sharks now head into their final game of the regular season knowing they have to win and hope the Dolphins or Roosters lose to clinch a top four spot.

Cronulla host the Storm, while the Dolphins head to the Titans, and the Roosters face their bitter rivals the Rabbitohs.

The Sharks won their first ever premiership in 2016 — to date their only Grand Final appearance since 1997.
