De Roon had been training with new Netherlands coach Dick Advocaat's provisional squad, and is now included in the final 28-man roster to travel to Portugal this weekend ahead of a friendly against Morocco (May 31) and Ivory Coast (June 4).

That will be followed by a World Cup qualifier against Luxembourg (June 9), who could yet call upon recent Boro acquisition Enes Mahmutovic.

Guedioura will link up with the Algerian national team for a friendly against Guinea (June 6) before his side kick off their qualification campaign for the Africa Cup of Nations 2019 against Togo (June 11). 

De Roon and Guedioura join Ben Gibson in being selected for international duty, while youngsters Dael Fry and Harry Chapman are with England's Under-20s at the World Cup in South Korea.
