Newcastle have completed their move for Atlanta United playmaker Miguel Almiron, the club have announced.
The 24-year-old Paraguay international has joined the Magpies on a five and a half-year deal for an undisclosed fee believed to be in the region of £20million, eclipsing the £16million they paid for England striker Michael Owen in 2005.
Almiron told NUFC TV: "I'm very happy and eager to start and to meet my new team-mates. The league is very competitive, this is a historic club, and Rafa Benitez himself were the main reasons why I am here now.
"I think it is a great responsibility, something beautiful for me, and I will try to offer the best I can to repay the trust the club put in me."
Major League Soccer side Atlanta United have appointed Frank De Boer as head coach.
The Dutchman is back in management for the first time since his short-lived spell at Crystal Palace at the start of last season.
De Boer, 48, was axed by the Eagles in September last year after five games and 77 days in charge.
Palace had lost all four of their Premier League matches without scoring a single goal.
"Frank De Boer has a distinguished background, both as manager and player, and we're ecstatic to welcome him to our club," Atlanta president Darren Eales told the club's website.
"When we began our search, we were determined to find someone who fit all of our criteria. In addition to meeting our club's core values, Frank's philosophical views for how to play unequivocally aligns with ours.
"He also has a proven track record of developing youth players, with many of them going on to star for top European teams."
