NEWCASTLE United have completed the signing of Daryl Janmaat from Feyenoord.
Janmaat, 24, has signed a six-year deal at St James’s Park.
The club have also announced that Mathieu Debuchy has joined Arsenal.
Janmaat said: “Newcastle is a fantastic club with a big history and a great stadium. I have also been told all about how great the fans are.
“This is the perfect move for me, and I am really looking forward to being with the team and getting started here at Newcastle.
“I think we are going to have a great season.”
Newcastle United manager Alan Pardew said: “We are delighted to bring Daryl to the Club.
“He is the perfect example of a modern full-back, someone who is good defensively but offers a real threat going forward as well.
“Daryl had an excellent World Cup and we are looking forward to him continuing that form for Newcastle.”
Meanwhile, Debuchy has joined Arsenal in a deal worth around £10m.
A statement read: “The club wishes to place on record its thanks to Mathieu for his efforts during his time at Newcastle.
“He leaves with all our best wishes for his future at Arsenal.”
