Antony on Thursday, completed his move to Manchester United, for a fee reported to be 95 million euros (£81.3m), making him the fourth most expensive signing in Premier League history.
The 22-year-old has put pen to paper a contract until 2027, with the option of an additional year.
The fee includes a potential five million euros of add-ons.
“This is an incredible moment in my career to be joining one of the most iconic clubs in the world,” Antony said in a statement on Manchester United’s website.
His fee is a record for an Eredivisie player, surpassing the 86 million euros of Frenkie de Jong’s move from Ajax to Barcelona three years ago.
Ironically de Jong had been United’s main transfer target for this season but they failed to secure him.
Antony has scored 31 goals in 134 club appearances for Ajax and Sao Paulo, and two goals in nine senior appearances for Brazil.
