Lazio have agreed a deal with Ajax for Dutch under-21 international Ricardo Kishna, according to the Amsterdam club's website.
Kishna completed a medical with the Italian side on Tuesday, ahead of signing a four-year deal that is worth around €1.2m per season for a fee believed to be around €4m (£2.9m), according to Football Italia.
The 20-year-old managed 26 appearances last season for Ajax, ending the campaign with five goals and five assists.
Kishna becomes the Biancoclesti's fourth Dutch player in their current squad alongside Stefan de Vrij, Edson Braafheid and Wesley Hoedt.
