Ilori, who was born in England before moving to Portugal, admits he rejected offers from several other clubs to make the move to Liverpool.
"This is the best league in the world and it has always been a dream of mine to come and play here," he said.
"It's never easy leaving the country you grew up in but it wasn't that difficult because I knew I was doing what I wanted to do.
"That made it easier. I was aware of a couple of other clubs that were interested but the way Liverpool dealt with it and spoke with me made it an easier choice," added Ilori.
"The club's history played a part but it was more about their approach and the way they dealt with me. I felt that this was the place to be.
"I don't think I'm such a fighter like a typical centre-back, but I can be aggressive when I need to. I like to take the ball out. I'm quick as well."
