The England international midfielder, 24, is under contract until June 2024 and is stalling negotiations on a new deal.
Mount is understood to be after a significant pay rise from his current wages of around £80,000 per week.
And he is reluctant to sign a huge long-term commitment like compatriot Reece James.
Chelsea‘s influx of players has also left Mount pushed down the pecking order.
Now the Daily Mail has claimed that he has appointed a new agent to look after him.
Neil Fewings from Wasserman Media Group is now in charge of Mount’s interests.
And the publication states that it is “the strongest indication yet that he is set to leave Stamford Bridge” at the end of the season.
Chelsea have insisted that they have made their final offer regarding a new contract and are reluctant to risk losing him for nothing next year.
And that could lead to them trying to cash in on their academy product this summer with both United and Liverpool waiting in the wings to pounce and sign him.

Mount’s father Tony has been representing the ace for the last 18 months since the star left previous management company, Stellar Football.
Now they have “sought more specialist assistance to negotiate with other clubs”.
And with mounting interest in the ace, with Newcastle also keen, the “change of approach may already be paying off”.
While it remains to be seen whether he will stay or go, rival English clubs have been put on alert by reports of a £50MILLION price tag.
