The young Dane has been linked with a move to England and Tottenham this season.
Asked about trialling at Chelsea as a youngster, Eriksen told the Guardian: "I was not disappointed, for me it was just to see how it goes, it was not really for going [there].
"It was another world. It was not like Denmark, or like this, where it is open and everyone can come [to training]. Everything was closed and if you are there as a 16-year-old and you have to be so closed, you lose a lot of things. And we thought the football was a little bit more power than what I wanted.
"Also Chelsea is such a big club, they have so much money that if they need someone for the first team, they just buy them. Ajax buy them if they are young and they see talent. And it's easier to go to the first-team here and that was also what I saw. At Chelsea it was like, Under-17 own world, Under-19 own world and then the first team another world. For a [young] player it was difficult to see how there could be a possibility."
