United States international Sergino Dest has signed a contract extension at Ajax, which will keep him at the club until 2022.
Dest, who made his Ajax debut in the 2-0 victory over PSV Eindhoven in the Johan Cruyff Shield, has played seven times for the reigning Dutch champions.
The 18-year-old also made his international bow as the U.S. were beaten 3-0 by Mexico.
He has been a regular for Ajax this season, having appeared in seven of their nine matches so far -- and started the past two games, including the crucial Champions League playoff second leg against APOEL Nicosia.
Dest, who was born in the Netherlands, could still change his national allegiance, having made only two international friendly appearances for the USMNT so far.
