Newcastle United have signed Nico González from Manchester City on a long-term deal on Wednesday.
Newcastle will pay an initial fee of £48 million ($65.4m) plus £4 million ($5.5m) in potential add-ons, sources told ESPN.
The Spaniard arrives as part of a new-look midfield for Newcastle, who have lost Bruno Guimarães to Arsenal and Sandro Tonali to Tottenham this summer.
"I'm really happy to be here at this amazing club," González told Newcastle's website. "I've only heard top words about the club and the city, so I am really excited to live here and to be part of this project.

"I've experienced playing at St. James' Park twice with Manchester City and it was really tough. The atmosphere was amazing and so passionate.
"I can't wait to experience that as a home player."

Like City, for whom Enzo Maresca has replaced the long-serving Pep Guardiola, Newcastle are transitioning from Eddie Howe's leadership to his replacement Matthias Jaissle.
Jaissle said: "I'm very happy to see Nico become a Newcastle United player. He brings serious quality and elite experience in a key area of the pitch.
"Nico is a really strong ball carrier -- somebody who can drive the team forward while staying composed under pressure. He also brings discipline defensively, he reads the game well and his physicality makes him well suited to the Premier League."
González previously played for Barcelona, Valencia and Porto before joining City, where he played 36 Premier League games and scored two goals.
