Scouts from the Old Trafford club are reported to have been sent to check on the 19 year-old in the recent Scotland under-21 victory over Finland at Pittodrie.
"He's got a natural engine and he has taken his opportunity and you sometimes forget how young he is," Ross said.
"Speculation is natural when you have success. He will be only too aware that if he flicks through the record books he will see how many players have burst on the scene then not lived up to their potential.
"But I think he will because he has everything going for him - ability, athleticism and temperament.
"We always had Scott Arfield picked out as a player of the future. I remember him coming through and the senior players were excited about him.
"Sometimes you are wrong because you need to make a yearly progression but he has done well."
Ross is backing his team-mate to produce the kind of form that has brought him Scotland Under-21 recognition when he lines up against the Dons.
He added: "He has enjoyed his run in the team. He thrives on the pressure of big games and playing at big stadiums in important matches.
"It's a good test of how his character stands up and he has been great for us this season."
