Crystal Palace have completed the signing of defender Jairo Riedewald from Ajax.
The Netherlands international, 20, has moved to Selhurst Park for an undisclosed fee and has signed a five-year contract.
He previously played under new Palace manager Frank de Boer at Ajax, making his first-team debut in 2013.
Riedewald is Palace’s second signing of the transfer window, following the arrival of Chelsea midfielder Ruben Loftus-Cheek on a season-long loan deal.
“It is a great opportunity to be working under De Boer once again,” he said.
