"We've got some players in our team who can score points so I'm sure our attack will come," Mannah said.
The former NSW prop was particularly impressed with Sandow who set up both of Parramatta's tries by Hayne and wing Cheyse Blair.
"That was the best I've seen Chris play for a long time. It was a really controlled game by him. He led the team and just steered us around the park really well," Mannah said.
Stuart's influence on Sandow was evident against the Panthers as the former Rabbitoh turned in a complete No7's game in a 60-minute display which was highlighted by a terrific kicking performance.
Co-captain Hayne, who led the side out for the first time, was also quick to praise Sandow.
"Chrissy's kicking game was probably the highlight of his game tonight and definitely was something that really put pressure on the Panthers," he said.
Mannah said having Hayne back for the Eels gave the 2012 wooden-spooners a massive boost.
