Who is Oskar Pietuszewski? FC Porto's latest signing from Jagiellonia Białystok

The teenager is seen as the next rising star from Poland.
Oskar Pietuszewski has now taken the next big step in his playing career after the teenage prodigy joined Portuguese club FC Porto this January.
One of the most promising youth football talents in the world has been acquired by FC Porto. After the Dragons spent €10 million to acquire the 17-year-old from Jagiellonia Bialystok, Oskar Pietuszewski became the most costly teenage football player to ever play in the Portuguese league.
Pietuszewski comes to Portugal with considerable hopes after fierce competition for his signing, including Atlético Madrid. He is ranked fourth in the world among players under 18 by CIES and is included among ‘The Guardian’s 60 finest talents in worldwide football.’
How did Oskar Pietuszewski burst onto the scene?
Pietuszewski has impressive senior experience already at the age of 17.
He was a star player for Jagiellonia Białystok in the PKO BP Ekstraklasa last season. He made a great impression on the youth side, and his performance was undoubtedly rewarded.
Pietuszewski attended the Academy of Jagiellonia Bávystok for his whole youth career. But his rapid growth encouraged the senior squad to give the gifted attacker a shot.
Pietuszewski debuted for the senior Jagiellonia Bávystok team at the age of 16. As he continued to develop at the club, other major European teams kept an eye on him. However, Porto were quick to sign the player before any other team could.
Oskar Pietuszewski’s international career so far
Pietuszewski’s early debut for the Polish senior national team alongside Robert Lewandowski was anticipated by many supporters. But that call-up is probably going to happen soon, but later. He might make his debut in the 2026 World Cup European play-offs.
He is still a standout player for Poland’s U21 team for the time being. Pietuszewski joins fellow Poles Jakub Kiwior and Jan Bednarek at Porto. With only four goals allowed in 18 league games and a seven-point advantage at the top, the Dragons are currently dominating the league.
