The Argentine youngster again declared his dislike for Real Madrid, explaining: "I am with the Atleti fans. If they do not like Real, then neither do I.
"I could only ever play for Independiente home in Argentina and the same is in Spain, where I could only consider playing for Atletico."
Asked who he would choose if Real or Barcelona made him offers, Aguero: "Only Atletico."
He added: "I hope Barca win the title this season."
