The Dutchman’s squad has been stretched due to injuries and suspensions in recent weeks the trio among those to have been sidelined.
Antony was ruled with a leg injury ahead of the clash with Leeds United at Old Trafford last week with Martial struggling with a hip problem having only just returned after a seven game absence off the bench against Nottingham Forest earlier this month.
McTominay meanwhile has an unspecified knock having not featured since the 3-2 defeat to Arsenal on 22 January.
The Carabao Cup final against Newcastle United follows three days later with ten Hag explaining last week he was confident Martial, Antony and McTominay would be available for the trip to Wembley.
Speaking ahead of this weekend’s test, the United boss offered a further update on the trio, telling reporters: ‘Maybe [they will be available].
We have to wait until tomorrow. Maybe one or two players can return, yeah.’
United were without Lisandro Martinez and January signing Marcel Sabitzer for Thursday’s draw with Barcelona with the duo available on Sunday and for the return fixture next week.
With Casemiro to sit out on Sunday against Leicester in the final game of his three-match ban, ten Hag will have options at his disposal.
‘You don’t want to miss them in the squad, in Barcelona. They are important players for our team,’ ten Hag said.
‘They are back in the squad, which is good. That will strengthen the squad, so we will have a good team on Sunday.’
