The 18-year-old winger has signed a five-year contract with the Seagulls, keeping him at the Amex Stadium until June 2031, with the fee undisclosed.
The Nigerian talent has emerged as one of Europe’s most exciting young prospects after impressing in Sweden’s top division this season.
AIK’s Head of Recruitment, Miika Takkula, praised his development and thanked him for his contribution to the club.
“It has been a great honor to have worked with Zadok. We will be excited to follow his continued career – and I speak for the entire club when I wish him the best of luck in the future,” Takkula told the club’s official website.
” In addition, I would like to clarify that this transfer is a result of the change in direction the club has already made, and of all the measures we have taken along the way. This is completely in line with the plan we have set, and we will continue to follow it.
“Here the choice of club is also relevant, Brighton offers a development environment that benefits Zadok and in the long term also AIK. Our vision, and the strategies we have worked on in relation to that vision, remain unchanged.”
