The deal, which includes a potential 5m euros (£4.3m) of add-ons, is the fourth most expensive signing in Premier League history.

The 22-year-old has signed a contract until 2027, with the option of an additional year.

"This is an incredible moment in my career to join one of the most iconic clubs in the world," said Antony.

"I'm thankful to everyone who has believed in me, especially my family, and all my coaches and team-mates, because I could not have got here without them.

"Playing under Erik ten Hag at Ajax was perfect for me and my development. His style of football and coaching brings out the best in me, and I am excited by what he has told me about his plans and ambitions in Manchester."

Antony scored 24 goals and provided 22 assists in 82 appearances for Ajax. He joined the Dutch champions from Sao Paulo in 2020 and played under Ten Hag.

He netted seven goals in 11 Champions League appearances for Ajax and scored twice in nine appearances for Brazil since making his debut in October 2021.
