Crystal Palace have announced the signing of defender Jairo Riedewald from Ajax for an undisclosed fee.
The centre-back has agreed to become Palace's second summer signing, after Ruben Loftus-Cheek's loan move from Chelsea, and joins on a five-year deal.
Riedewald, pictured top against Manchester United in last season's UEFA Europa League final, is manager Frank de Boer's first permanent signing at Sehurst Park.
"The Premier League is a great competition to be involved in and it is a great opportunity to be working under Frank de Boer once again having been with him at Ajax," Riedewald told cpfc.co.uk.
Palace start the new Premier League campaign at home to newly-promoted Huddersfield Town on Saturday, 12 August.
