The Eels are within reach of the top of the NRL ladder, but making the jump will be no walk in the park with the Sharks entering Round 13 having won six of their last seven matches.
Here are five things you need to know about the clash.
Gutherson’s 100th Eels Game
Eels Captain Clint Gutherson will lace up the boots for the Blue and Gold for the 100th time on Sunday.
He played five games for Manly, before being picked up by the Eels in 2016.
The fullback is enjoying good form so far in 2020, with four tries, 11 try assists and an average of 198 running metres per game.
This week he wrote a heartfelt letter to fans about why he loves playing in the Blue and Gold, which you can read here.
Playing for the Johnny Mannah Cup
The Johnny Mannah Cup is an annual fixture between the two sides that honours former Eels and Sharks player Jon Mannah.
An Eels junior who joined he Sharks in 2009, Mannah returned to Parramatta ahead of the 2012 season.
He sadly passed away after losing his battle with Hodgkin's lymphoma in January of 2013, aged just 23.
Since his passing, the two clubs have played for the Johnny Mannah Cup in their first meeting each season.
The Eels claimed the cup after a 24-12 victory in Round Four of the 2019 season.
Trip to Kogarah
The Eels love playing at home at Bankwest Stadium but this week’s showdown is a fair drive away at Netstrata Jubilee Stadium.
There has been a fair bit of traffic on the surface with the A-League also playing fixtures at the venue.
With wet weather this weekend, which team will cope with the playing conditions better?
The Eels are sitting pretty on a 10-2 record, but their recent wins have been gritty and narrow.
They will have to clean up a few areas of their game to get a convincing win on Sunday.
The Sharks have quietly climbed up the ladder and are closing in on the top four after a slow start to their season.
They have won six of the past seven matches.
However they lead the NRL for the highest number of missed tackles, with an average of 36.75 a match.
Ray Stone returns from injury for the Eels and replaces Brad Takairangi on the bench.
Ryan Matterson will sit on the sidelines for another week, following a head knock in Round 11.
Josh Dugan, Jesse Ramien and Matt Moylan have been named and are expected to play despite managing hamstring injuries.
Rookie Jackson Ferris is both injured and suspended.
Siosifa Talakai moves to the second row, with Briton Nikora dropped.
Moylan returns in the halves in place of Braydon Trindall.
