The 14-year-old made two appearances for his country at under-16 level in the recent Victory Shield campaign, and despite reported interest from Chelsea has decided to move to Merseyside.
The news was revealed by MK Dons chairman Peter Winkelman, who has wished the starlet the best of luck with his move.
“This is the opportunity of a lifetime for Seyi and his parents which has proved far too difficult to turn down,” the executive told the club’s official website.
“There has been a lot of interest and speculation regarding Seyi which he coped with admirably.
“We are extremely proud to have Seyi in our record books as our first schoolboy to receive an international cap.
“Everyone at the club would like to wish Seyi the best luck in his future and we all look forward to the day he runs out at Anfield,” he concluded.
