The Red Devils are hoping to secure the England international, who only has a year remaining on his Blues deal.
Mount, who the British press claim prefers a move to United over other clubs, was praised for a specific reason by his former boss Thomas Tuchel.
He stated in late 2021: "It's not a statistic [higher win percentage with Mount in the team] which guarantees you to start because this would be too easy.
"But it is something we are aware of and we will not deny that having Mason brings a certain attitude and an aura and a mentality on the field.
"It is very hard to drop him because even if he has a not so good game, you'll always get full energy and positivity and a wonderful approach."
