Kaka has welcomed new Real Madrid signing Nuri Sahin.
The Borussia Dortmund star is joining Real this summer.
"Sahin I know well, I know he has had a great season at Borussia Dortmund and a great effort was made to get him to Madrid," said Kaka.
Asked about Real's pursuit of Athletic Bilbao striker Fernando Llorente, Kaka added: "He is a great player and could play for any major team in Europe, but Madrid is where he will always do better.
"Let's just say he's an excellent footballer."
