Swansea sign Ajax defender Mike van der Hoorn
The young defender will join the Premier League side ahead of the 2016-17 campaign.
Swansea have completed the signing of Dutch defender Mike van der Hoorn from Ajax.
The centre-back, who has represented Holland at under-21 level, made 43 first team appearances for Ajax after joining from Utrecht three years ago.
Swansea were looking to bring in a defender after Kyle Bartley went out on loan to Leeds United, and manager Francesco Guidolin was desperate to snap up the 23-year-old from the Eredivisie.
On Tuesday Swansea also completed a move for the defenders compatriot Leroy Fer, who joined from Queens Park Rangers.
