Newcastle United have clinched the signing of Christian Atsu on a four-year deal.
The winger spent this season on loan from Chelsea.
And Newcastle have taken up a £6.2million buy option in the Ghana international's loan.
Manager Rafa Benítez said: "We are happy to sign a good player.
"He's shown us that he's a good professional and someone who is very keen to learn and improve.
"Christian has been a key part of our promotion campaign and he wants to help us to build something for the future."
The transfer is subject to Atsu successfully reapplying for a work permit.
