The 14-year-old, who was also linked with a move to Chelsea, has joined the Reds’ academy.
“This is the opportunity of a lifetime for Seyi and his parents which has proved far too difficult to turn down,” MK Dons chairman Peter Winkelman 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.”
