Cronulla have had the wood on Parramatta in recent years but the Eels got the better of them in 2020 and are coming into this game unbeaten after a strong start to this season.
The Sharks had won six of their previous seven clashes with Parra before last year's 14-12 loss in round 13 in which the Eels scored one less try than their opponents but got home on the back of a Mitchell Moses penalty goal.
Brad Arthur's side kicked off 2021 with a comeback win over Brisbane but were more impressive last Thursday when they vanquished premiers Melbourne in a slugfest at Bankwest Stadium.

The rundown
Team news
Eels: In the only change to the 17, Ryan Matterson (concussion) will not play after his heavy head knock in the impressive win over Melbourne.
Matterson is replaced in the starting back row by impressive off-season recruit Isaiah Papali'i. That brings Ray Stone, who makes his NRL return from a knee injury, onto the bench.
The Eels will be without centre Waqa Blake for at least a month after he suffered a calf injury at training last week while Bryce Cartwright (broken jaw) and Michael Oldfield (knee) are scheduled to return between rounds four and six.
Haze Dunster and Joey Lussick were trimmed from the reserves list on game day after Jordan Rankin and David Hollis were left out 24 hours before the match.
Parramatta have a 76 per cent winning record at Bankwest Stadium.
Sharks: Utility Connor Tracey will step up from the interchange to replace centre Mawene Hiroti, who was subbed out for Tracey just after half-time in the loss to Canberra.
Hiroti, who stepped in for the suspended Jesse Ramien in round two, has slipped all the way out of the 17 with Teig Wilton promoted to take Tracey's place on the interchange.
It will be at least a month before we see Royce Hunt (knee) and Siosifa Talakai (shoulder) who have had their returns delayed after initially being expected back early in the season.
Ramien will return from suspension in round five while star half Shaun Johnson is due back in round seven or eight from an Achilles injury.
Hiroti and Andrew Fifita were cut from the reserves an hour before kick-off after Nene Macdonald and Braydon Trindall were the two players omitted on Friday night.
The Sharks have won six of their past eight games against the Eels.

Key match-up
Nathan Brown v Toby Rudolf: Two locks who hold the key to their team's fortunes. If you'll pardon the pun.
Neither player will take a backward step - Brown is built low to the ground but has a habit of getting under the skin of opponents while Rudolf is a towering forward who tends to run over the top of his rivals.

Stat attack
Maika Sivo has scored 39 tries in just 48 appearances for Parramatta in a little more than two seasons in the Telstra Premiership, including two pearlers in last week's win over the Storm.
Despite driving rain, Sivo showed superb skill to collect each kick in the wet conditions, particularly his second try late in the game which brought Melbourne to their knees and the Bankwest Stadium fans to their feet.
