Erik ten Hag has sent a pointed message to Antony ahead of Manchester United's League Cup clash with Barnsley on Tuesday night.
Antony is yet to start a Premier League fixture this term, with the Dutchman insisting the £86million forward has to 'earn the right' to be included in United's starting XI.
On the Brazil international, Ten Hag said: "Tomorrow you will see what the line-up will be.
"We have training every day and the players have to earn the right. When the attitude is good and show performances in training, then they will play."
Antony has featured just once for United all season - a one-minute cameo during the Red Devils' injury-time defeat to Brighton last month.

Tuesday's League Cup tie against League One Barnsley should provide Ten Hag the perfect chance to rotate his starting line-up and give minutes to those players who haven't featured much this term.
But at least five United aces won't be involved, with Luke Shaw, Rasmus Hojlund, Mason Mount, Leny Yoro and Victor Lindelof out of action.
On their availability, Ten Hag added: "Luke Shaw is progressing, but not yet ready to be selected.
”We have a plan in our head when he can be ready, but you’re always dependent on how the progress will go and you can’t think, you can’t make a suggestion, because there are so many factors, a plan can accelerate or slow down.
"They [Hojlund, Mount, Yoro and Lindelof] are not ready for tomorrow. We will see, our progress will continue. But I hope I have selection headaches. Last year I also had headaches, but there were no players available.

And on the importance of the League Cup, Ten Hag commented: "It’s about winning trophies but I don’t talk only about this, you guys are talking about how we have to win.
"So no doubt we're aiming for a trophy and we take it seriously. I wouldn’t say they are insignificant, the FA Cup and Carabao Cup. They’re significant. I see the attention from all the teams, all the owners, all the managers, when they win the trophies like Liverpool last year, and I see all the teams battling for it.
"We want the same. In football, to win trophies is very and our aim is to win all the games if possible."

United's clean sheet would be kept intact though, with Andre Onana matching Cameron Archer's spot-kick with a strong save, providing the away side with a platform to go on and win the game.
