Atletico have been following Pato's progress and will move quickly for the youngster should he make an impact in the Argentine championship this season.
The youngster said: "I'm proud that they compare me with him, but El Kun is a genius... I've hardly begun to take my first steps and I know that I need to learn a lot. I want to continue like this, slowly, calmly... The truth is I could not have hoped that so many things could happen for me in such a short time."
