L'Equipe says Rabiot sees United as giving him the opportunity to "muscle in" on Didier Deschamps' team selection.
They claim that he sees his place in Ten Hag's team as "almost guaranteed" due to his "weak" competition.
The claim comes following Rabiot's exclusion from the main World Cup squad in 2018, as his boss instead tried to place him on the reserve list.
Rabiot controversially then refused to be on the reserve list and withdrew from it.
The midfielder is believed to have since patched things up with Deschamps and is fighting to be included this time round.
