Georginio Wijnaldum has become the third most expensive signing in Newcastle's history after putting pen to paper on five-year deal.
Steve McClaren: "This signing is a real statement for the club. It is a big transfer for a very good player and I am delighted to have Gini here at the club.
"He has lots of energy and a great tempo to his game. He is very skilful, but is also capable of playing box-to-box, and - importantly - he can score goals.
"He is at the right age and the right fit for Newcastle. He is a leader as well and you will see that. He is someone who always wants the ball, can deal with it, and we need that kind of character in the team."
Wijnaldum, a Rotterdam-born player who came through the ranks at Feyenoord, made 130 appearances for PSV and scored 47 goals during his four seasons at the Philips Stadion.
Forty of those appearances and 16 of the goals came as captain last season as the club cruised to the Eredivisie title, finishing 17 points ahead of closest rivals Ajax.
He has 19 senior caps and represented his country at the World Cup finals in Brazil last summer.
