Real Betis have secured the services of Portuguese right-back Nelson from Benfica.
The 25-year-old, who has spent the last three seasons with Benfica, has signed a five-year deal with Betis.
Nelson is Betis' second signing in as many days following the arrival of Nery Castillo, who had been on loan at Manchester City last season.
The full-back had been interesting Aston Villa during the close-season, although they eventually opted for Middlesbrough's Luke Young.
The Cape-Verde born defender has been called-up by Portugal but is yet to win a full senior cap.
