Kaka struck in the 3-1 win at the Bernabeu.
He said: "I feel fine on a personal level. I'm playing well and I'm happy for it. We have a whole week to prepare for Getafe. I had a chance to net a header as soon as the game started and I later entered the box.
"We'll have to fix some things because we can't keep conceding openers. The Bernabeu has always helped us. These comebacks showcase character and the crowd feels it."
