The 20-year-old winger joined Arsenal's under-23s this week after signing a professional contract, and cannot wait to get going in north London.
Lewis told arsenal.com: "No, it's really an unbelievable feeling. It feels really good right now.
"I started playing football when I was maybe five years old at my local club called Stakkevollan IF, then I played there until I was about 12, then we moved and me and my brother both changed teams, so we joined the other team Tromsdalen, where I went to play for the first team. But before that I was in another team called Tromsø, who were in the top division at that time, before I came back in 2017 and then I really stayed at Tromsdalen for two years until last year where I moved to Fram Lavrik to get more opportunities playing
"My playing style is very direct. I like to dribble a lot, I like to express myself on the field, so they can expect a show from me, yeah!"
Lewis admits his family support Arsenal.
He added: "Yeah, all of my family are Arsenal fans. When I was growing up, I really looked up to players like Adebayor, he was a really big role model for me, as well as Thierry Henry, and yeah, just to mention some of them."
