Marvin Emnes has completed a permanent switch from Middlesbrough to Swansea.
The 26-year-old Dutchman, who has had two successful loan spells with the Swans, put pen to paper on a three-year deal after negotiating a medical on Wednesday.
A statement on the club’s official website, www.swanseacity.net, said: “Swansea City have completed the signing of Middlesbrough winger Marvin Emnes for an undisclosed fee.
“Following two previous loan spells at the Liberty, Emnes made his move permanent by signing a three-year deal after he completed his medical today.”
Emnes, who spent a month on loan at the Liberty Stadium during the 2010-11 season, returned in January and scored one goal in nine appearances.
He joined Boro in a £3.2million from Sparta Rotterdam during the summer of 2008 and made a total of 161 appearances for the Teessiders, scoring 31 goals.
