The two teams meet on Sunday.
"I said that to a friend while watching their game against Getafe," Yuri told Marca.
"You can praise many things about their play, but in terms of the playing squad, Real Madrid have the best in the world, without doubt.
"They have a lot of players, all internationals, all of them really good and when one comes on, it seems like they're better than the other.
"But we have our strengths and we're in really good form, which we want to show and bring on to the pitch."
