The Argentine was part of the team that thrashed Tianjin 6-0.
He said: “I must continue to improve because I started the preseason late, but I’m happy. A striker always likes like to score goals.
"The team is more mature this year and it’s obvious on the field. We’ve built a great squad for the new season. We are going back home to Madrid very happy and we will start preparing for the Supercup."
