The 28-year-old hasn’t made a single appearance for his club since a 3-0 home defeat against Bournemouth six weeks ago.
Martial, according to Ten Hag, missed last weekend’s 2-2 draw with Tottenham through illness.
The Daily Mail claim the Dutchman has subsequently asked Martial to train away from the rest of the first team squad.
Responding to those claims, Phillipe Lamboley, Martial’s representative, told Sky Sports: ‘What is said about him is completely false.
‘He was not excluded from the group and he has no problem with [Erik ten Hag].
‘Anthony has been in Manchester for nine seasons and if he was not a great professional then he would not have been at the club for so long.
‘He is simply going to undergo a small operation on his adductors, which he should have done for a while and which did not allow him to be 100 per cent, so he will do it now.’
‘Anthony will not leave and will stay until his contract ends in June,’ Lamboley added.
Martial received offers from both Marseille and Fenerbahce earlier this month but wants to stay and fight for his place before leaving on a lucrative free transfer.
United’s hopes, meanwhile, of signing attacking reinforcements this month appear remote, despite fresh investment coming from Sir Jim Ratcliffe.
United are said to interested in the possibility of signing Karim Benzema on a short-term loan deal, but it remains to be seen whether or not the veteran forward can engineer his exit from Al Ittihad.
