QPR was relegated from the top flight after finishing bottom of the Premier League last season, but Austin is all but certain to return to the Premier League.
Newcastle United and West Ham United have also emerged as potential suitors for the star striker.
The English international has proven to be a consistent scorer over his entire career, as he has notched up 220 goals in 355 total appearances.
This includes 39 during his stint with QPR, and he has started off the season with a bang in the Championship with four goals in five matches.
Man United have struggled for goals in the Premier League this season, and the Red Devils suffered their first loss of the season against Swansea on Sunday.
