The report also suggests the Dutch sensation is on the radar of the German club Eintracht Frankfurt.
The 19-year-old has represented the Eredivisie club’s U-21 side.
Being a youth product of Eindhoven, Lonwijk has made 24 appearances for the reserve side Jong PSV.
The teenager can be deployed either as an attacking midfielder or a wide midfielder.
He has scored 20 goals in the Dutch club’s U-19 team.
Lonwijk has earned nine caps so far for his country’s U-19 team.
Why Should Leeds sign?
The Dutch wonderkid could inherit the position of the Whites midfielder Pablo Hernandez. And with the Spaniard is nearing the twilight of his career, Marcelo Bielsa is certainly in need of the player with a similar archetype.
Moreover, Lonwijk could form a great partnership with Patrick Bamford up in the front.
The Dutch club is yet to renew the youngster’s contract and Leeds could maximize their chances if they get promoted to the Premier League next season.
The Argentine manager has the reputation of developing the young players in his U-23 squad.
The defeat against Sheffield United saw the Elland Road side slip a position down the table.
With only a handful of matches to be played, the Whites are battling hard to secure their promotion to the Premier League.
