Rhian Brewster has become Sheffield United's record signing.
The England U21 striker has left Liverpool for a reported £23.5million (€25.95m), despite never having played a Premier League game.
Liverpool are believed to have inserted a 3-year buy-back clause into the deal, and will receive 15 per cent of any future sale from Sheffield United.
"At the top of the pitch we have one of the country's hottest properties from Liverpool and for him to sign permanent here is fantastic for everyone concerned," United manager Chris Wilder said.
"There has been a lot of interest in him over the summer, a lot of speculation about who we were going for, but he has been our number one target and I am delighted to have secured his services.
"If you look at the signings we have made throughout the summer, it bodes well for the future of the football club.
"He's a talent, as are a lot of the younger players we have brought in, whether that's Oli Burke, Max Lowe, Jayden Bogle or Aaron Ramsdale, they are the profiles of the players we wanted to bring in during the summer, and we're delighted we have done it.
"He's a natural goalscorer. He finishes from any aspect, whether it is in the air or whether it's spectacular goals, free-kicks or off his shin - he has a lovely habit of scoring goals, which is crucial in the Premier League."
Brewster scored 11-goals in 22 appearances while on loan at Swansea City last season, a spell that he feels stands him in good stead for the move to Bramall Lane.
"I am ready to come in and show everyone what I've got. It is a team that creates a lot of chances, the three at the back, overlapping, they get crosses into the box and that's my game - being in the box, finding space and one and two touch finishes.
"That's what I am going to try and do, and try and score goals for Sheffield United."
Brewster's unlikely to be the only departure from Anfield before the transfer window closes on Monday.
Xherdan Shaqiri was withdrawn from the squad to play Arsenal in the Carabao Cup after interest from an unnamed club intensified.
Marko Grujic and Harry Wilson could follow, but Burnley withdrew their bid for the latter on Thursday.
