The 25-year-old striker has impressed this season for his club Zulte Waregem, with six goals from 13 games.
Habibou has returned to form this term, after missing most of last season through injury - but now he is attracting major interest from England.
Sky Sports understands that Habibou has trained with both QPR and Leeds this month - firstly with the London outfit and only this week with United.
Now both teams are understood to be impressed and are hopeful of finalising a deal with Zulte.
The Central African Republic-born striker has previously had trial stints with West Ham United and Brighton.
