Barcelona have completed the signing of right-back Sergino Dest from Ajax in a deal worth up to €26.2m (£23.8m).
Ajax will receive an initial fee of €21.2m (£19.2m) and an additional €5m (£4.6m) in add-ons for Dest, who has signed a five-year deal at the Camp Nou with a buy-out clause set at €400m (£362.9m).
Barcelona have beaten off competition from Bayern Munich to land the 19-year-old United States international, after seeing an offer to take Max Aarons on loan rejected by Norwich City.
Sky Sports News reported earlier this month that Barcelona had agreed personal terms with Aarons but the deal broke down as Norwich wanted to include an obligation to buy at the end of the loan.
The German giants are also in the market for a young right-back and have rivalled Barcelona for Dest and Aarons while also expressing an interest in Brighton's Tariq Lamptey. สูตรบาคาร่าฟรี ป๋าเซียน
