Liverpool have completed the signing of Origi but the 19 year-old will be loaned back to former side Lille for next season.
Origi arrives at the club after being heavily linked with a move since the World Cup.
And upon completing his transfer during the squad’s pre-season tour of America the youngster said: “I am very, very happy and delighted a club as big as Liverpool showed interest in me. I’m very excited.
“I know it’s a club with a great history, great fans and a lot of great players. For me, Liverpool is one of the greatest clubs in the world and I’m very excited to be part of this great history.”
