Slovenian international goalkeeper Jan Oblak has agreed a six-year deal with Atletico Madrid, the La Liga champions confirmed on Wednesday.
The arrival of Oblak from Portuguese champions Benfica follows that of Miguel Angel Moya from Getafe last month.
Atletico are replacing Belgium goalkeeper Thibaut Courtois, who has signed for Premier League giants Chelsea, with Dani Aranzubia out of contract with the Spanish side.
Atletico sporting director Jose Luis Caminero expressed his delight at the deal which is subject to a medical.
"Jan Oblak is a goalkeeper with a lot of quality and a very promising future," said Caminero.
"He'll offer us much with his enormous array of qualities. He's one of the most promising goalkeepers in the world and we're very happy that we can count on him. This is great news for our club."
The 21-year-old joined Benfica from Olimpija Ljubliana in mid-2010. He helped Benfica to the domestic treble and the Europa League final last season.
Oblak made his debut for the Slovenian national team in the 2009/2010 season.
