The talented young Belgian joined the Reds from Lille during the 2014 off-season after impressing at the World Cup in Brazil, but was immediately loaned back to Les Dogues, scoring eight goals in 33 League appearances.
Having now moved to England, Origi believes he will benefit from the experienced Liverpool squad and has backed himself to have a good first season in the Premier League.
"I am a better player than a year ago when Liverpool decided to sign me and at this stage of my career I am learning a lot of things," the 20-year-old is quoted as saying by the Mirror.
"I just feel that now I am at the right moment and at the right place to be able to become a really good player.
"I am always confident about myself but now I am in a good place. I still have a lot to learn but I am playing with experienced players and a very good staff that can help me improve every day."
