Swansea have completed the signing of Mike van der Hoorn from Ajax on a three-year contract.
The 23-year-old joins a day after the Swans confirmed the arrival of his compatriot Leroy Fer from QPR for an undisclosed fee.
The former Holland Under-21 international also strengthens manager Francesco Guidolin's central defensive options following Kyle Bartley's loan move to Leeds.
