Old Trafford chief Jose Mourinho has played the Frenchman for just 60 minutes in all competitions this season.
Chelsea, Tottenham and Inter Milan are keeping a watchful eye on the situation regarding Martial, whose sole appearance this season came in the defeat to Brighton.
But despite the ace clearly not being part of his manager's plans, Ed Woodward and the United money men want to keep him at the club.
The 18-cap France international, 22, has cost £44.5million so far with further clauses yet to be activated that could push the fee as high as £57.6m.
SunSport has learned Monaco are due half of any profit meaning United would have to flog Martial – whose contract can be extended up until June 2020 – for upwards of £100m to make just £30m on the goalscorer.
Woodward will not sanction a sale to a Premier League rival and, after crunching the numbers, does not see any value in allowing Martial to join a European club.
As well as the financial concerns, United bigwigs still believe they have a potentially world-class player on their hands.
And a January loan to a foreign club is being considered in order to hand Martial some much needed game time and protect their asset.
Martial arrived at Old Trafford with plenty of hype but has since seen compatriot Kylian Mbappe steal the spotlight after his success with Monaco, Paris Saint-Germain and France.
He has fired in 36 goals in 137 games for the club but missed out on France's World Cup-winning squad this summer.
