While the 20-year-old says he has no intention of leaving just yet, he admits it has always been his aim to play for Spanish giants Barca.
"It's not just a dream, it's an ambition for me and I think it is achievable," Armenteros told Voetbal International.
"It is not right for me now to move to a bigger club right now. Heracles feels like a Lamborghini to me.
"Here I play every week and in a good league. For now, it is all that matters, and then comes the rest."
He added: "I hate Real Madrid. It's terrible, this degradation to football.
