Erik ten Hag has hailed Antony as the 'missing link' for Manchester United following Sunday's 3-1 win over Arsenal.
The Brazilian scored on debut as United claimed their fourth successive Premier League victory.
"I think we have already seen what a threat he is," ten Hag told reporters. "Speed and creativity are a real threat in the Premier League. And he is a part of it.
"And I think we missed a player on the right wing because all the players that can play there like Jadon Sancho, like Marcus Rashford, prefer more the centre or the left side.
"Now, we have the one who can play really good over the right wing, so there was a missing link. Now, today's first performance here, he did well, but he can step up.
"I know him from Amsterdam. I know this is a different league, but there is potential and he will get that. He will be even better than he was today. But I would say today already, it was a great goal. Although, I must mention all the goals today were team goals."
