Real Madrid have confirmed they have reached an agreement with Benfica over the transfer of Argentina winger Angel di Maria.
His switch to the Bernabeu, on a six-year deal, is reported to be worth 25 million euros (£20.3m).
The 22-year-old, who is currently part of his country's World Cup squad, becomes Jose Mourinho's first signing since taking charge at Real last month.
Di Maria moved to Portugal in 2007 from Argentine side Rosario Central.
The attacking midfielder has started all four of his country's World Cup matches so far, playing on the left side of a central three - although he has not yet hit top form in South Africa.
Di Maria won the World Under-20 Championship with Argentina in 2007 and scored the extra-time winner against Holland in the final of the 2008 Olympic Games.
But he especially caught the eye of Europe's top clubs last season as he helped Benfica to a Portuguese league and cup Double.
Despite reported interest from elsewhere, Di Maria has opted to become the first player to join Mourinho in Madrid since the ex-Inter, Chelsea and Porto boss signed a four-year deal with the Spanish giants on 31 May.
