Manchester United boss Erik ten Hag says Antony will bring "quality" and a "fighting spirit" to Old Trafford.
The Brazil attacker's move from Ajax was confirmed today.
Ten Hag said, "We (Ajax) signed him the first time he was in Europe and we supported him to find his way. From the first moment, he really impressed in terms of his football qualities and as a person. He's a fighter and someone who has a real willingness to win games, I like that. He showed that from the first moment in Amsterdam, from the first game with the winning goal.
"That is what he always contributes to the team – a fighting spirit who makes actions and I expect the same from him here in Manchester.
"He's a player with a winning mentality and someone who is creative. He likes to dribble, he sees the final pass, he can score a goal and I think the fans will be excited by him and the way he plays his game.
"We want to compete with the best clubs and we want to win every game so you need a good squad. A squad that also has competition in but also during the season you have injuries, suspensions and loss of form so then you need substitutes to fill in the role. You need quality and I think now we have a squad which has the quality."
