Tottenham have signed Brazil defender Emerson Royal from Barcelona for 30m euro (£25.8m) on a five-year contract.
The 22-year-old has spent the past two seasons at Betis, scoring five goals in 79 games.
Emerson, who joined Barca from Brazilian side Atletico Mineiro in 2019, featured in Brazil's run to the Copa America final this summer.
He will compete for the right-back slot at Spurs with Japhet Tanganga and Matt Doherty.
The Premier League leaders are looking to offload full-back Serge Aurier.
Emerson played more minutes than any other Betis player last season as they finished sixth in La Liga to qualify for the Europa League.
