Mannah said he was annoyed at once again having to discuss non-football matters with the press.
"The frustrating thing is we're spending time again focusing on things outside of footy," Mannah said.
"It'd be nice to just come here and talk about the positive result we had against Melbourne, talk about the rest we had on the weekend, how fresh we're feeling now and how we can prepare and hopefully get back-to-back wins this week.
"The frustrating thing is we're not talking about that.
"We're talking about off-field things and what management could've done and what's happening over there."
The Eels veteran said the team was surprised by the news Foran could pull the pin on his deal, but was in no mood to discuss how the backflip would impact the club's future.
"It'll be a huge loss of energy to focus so much on it," he said.
"For us, it's business as usual.
"If we focus so much on what could happen and what could possibly happen next year, I feel we're wasting a lot of energy ... when we could be focusing our energy on playing footy and preparing well."
