FC Barcelona’s Spaniard has announced the signing of right-back Sergino Dest from Ajax for 21 million euros plus five million more variables.
Dest, who has signed a five-year contract, will have a termination clause of millions of euros.
The Catalan club said the new signing would be on Friday afternoon.
On his official website, Barcelona said: “Sergio Dest combines many of the necessary qualities for a complete defense: attack when asked, forge defensively, unperturbable on property and artistic with him.
“The defender has the ability to move players forward and his speed is a hallmark of advancing and defending. These qualities will now be displayed with the Barça jersey, a challenge for a young and brave winger.
The 19-year-old American is coach Ronald Koeman’s first recruit.
