Crystal Palace have signed Netherlands defender Jairo Riedewald from Ajax on a five-year deal for an undisclosed fee.
The 20-year-old Ajax youth academy product made his debut for the Eredivisie outfit in 2013 and has gone on to make 93 appearances for the club in all competitions.
It was Palace’s new boss Frank de Boer who oversaw Riedewald’s progression through the Ajax ranks to the first team and his move to London reunites the two.
Riedewald is Palace’s second signing of the transfer window after Chelsea midfielder Ruben Loftus-Cheek joined on a season-long loan deal.
“It is a great opportunity to be working under De Boer once again,” Riedewald, who has three caps for the Netherlands, told the Premier League club’s website.
De Boer added: “Jairo Riedewald is a player I know well through my time at Ajax and I’m glad that he’s now coming to join us at Crystal Palace.
“He will be an excellent addition to our squad, Jairo is a young player but already has a lot of experience. I know he is looking forward to playing in the Premier League.”
The versatile Riedewald has featured at centre-back, left-back and defensive midfield in his career to date, and registered the highest pass completion percentage in the Dutch league last season with 92 per cent.
The defender has featured at U15, U16, U17, U19 and U21 for the Netherlands and has earned three senior caps since making his debut in September 2015.
