Premier League giants United were paired with French side Saint-Etienne in the last 32 of Europe's second-tier competition on Monday, pitting the Pogba brothers against each other for the first time in a competitive game.
"I want two draws between my children, I don't want anyone to lose, even if I know that unfortunately one will be eliminated," said Yeo Moriba, who plans to attend both legs of February's knockout tie.
Jose Mourinho's United will be heavy favourites to advance but Moriba added her sons "are very happy to cross paths on the pitch".
Paul Pogba, 23, became the world's most expensive player when he rejoined United from Juventus for a record 89 million pounds (105 million euros, $116 million) in August.
Elder brother Florentin is three years older and represents Guinea, the country of his birth, along with twin brother and Sparta Rotterdam forward Mathias at international level.
