Parramatta hooker Kevin Kingston says he can't wait to face his former Cronulla teammates on Sunday at Toyota Stadium, but is expecting no favours as the Eels aim to keep alive their slim NRL finals hopes.

Kingston, who spent four years at the Sharks, has been one of the unsung heroes in Parramatta's recent good run of form, and scored his first try in the blue and gold in the Eels' shock 27-8 win over the Bulldogs last week.

The 26-year-old admits he is one of the less heralded members of the side and said he is happy to sit under the radar and let the likes of Daniel Mortimer and Jarryd Hayne grab the spotlight.

"I am just happy to do my job for the team and be playing regularly," he told AAP.

"I think one of the main reasons we have had a good recent run of form is that we have had a settled one, nine, seven and six with Daniel Mortimer and Jeff Robson doing a good job in the halves and Jarryd Hayne playing brilliantly at fullback."

Kingston is still close mates with Ben Pomeroy, Brett Kearney and Paul Gallen and is expecting nothing less than a battle on Sunday and said he is fully expecting some stick from the home crowd.

"I am sure I will be getting dog's abuse!" he said.

"But I am really looking forward to getting back there, I had a great four years at the club and still have a lot of mates there, and also it is a close drive to the stadium for me."

Kingston is also aware that the Eels need to win every game this season to have any realistic chance of reaching the semi-finals, but said the victory over the Bulldogs was a massive confidence booster.

"It showed that on our day we can beat anyone but we need to produce those type of performances week in week out," he said.

"Reaching the final has not been discussed, because if we do then we are in danger of losing focus."

The Sharks will be without injured star five-eighth Trent Barrett on Sunday with Blake Green filling the No.6 shirt and the 22-year-old is determined to make the most of his opportunity against the club he started his career with.

"It's obviously big shoes to fill but I'm looking forward to playing against my old club," he said.

"I played against the Eels last year but I came off the bench and I played a utility role so this is the first time I play in my preferred position against them so it's going to be a big challenge because they're going really well."
