He told Radio Marca: "The goalkeeper I like the most right now is Oblak, because of the way he moves in the goal. Then I would put Courtois and then (Marc-Andre) Ter Stegen who does very good things but it is not the style that most I like.
"I'd pay a little more for Oblak than for Courtois."
On news that Iker Casillas is returning to Madrid, Gonzalez added: "It is always important that a person who has lived with Real Madrid returns and contributes his experience. I am very happy that Iker is back to contribute his ideas to the foundation."
