Embattled Wests Tigers five-eighth Mitchell Moses will finally join Parramatta by Tuesday morning, according to uncle and Balmain great Ben Elias.

Moses' future has been a hot topic in the NRL since agreeing to a long-term deal with the Eels last month following the club's sensational decision to withdraw an offer.

But after speaking to his nephew on Sunday night, Elias predicts a welcome end to the saga.

"I told him he missed more tackles than he made [against Souths] and he said, 'Uncle Ben, I'm just not there'. He's not there and he hasn't been there for the past two weeks," Elias told AAP on Monday.
