Jackson admits growing up admiring the now Al Nassr striker and has been using the Portuguese's "Siuuu..." celebration after scoring for the Blues.
He said: "The siuuu is like important. Just when I score hat-trick, I’ll do that one.”
Jackson did as much last season after scoring a treble against Tottenham.
He also stated: “When I was growing up, I loved Cristiano Ronaldo. I had his name on a shirt that I always wore. Not an actual shirt because they are expensive, so you don’t buy them. But I had a shirt that I put 7, Ronaldo on with a pen. I did it myself when I was a kid.
“Of course, I would pretend to be him, but it was difficult to watch his games because you needed to pay. We would go to my friend’s house, everybody. We would watch in a large group, never just with one person in the house. All my friends, we’d all go to one house to watch Real Madrid.”
