Liverpool have completed the signing of 18-year-old Scottish right-back Calvin Ramsay from Aberdeen on a five-year deal for an initial £4.2m.
The deal for the Scotland Under-21 player also includes £2.5m of potential add-ons and a 17.5% sell-on clause.
There are no plans to send Ramsay on loan and he will join up with Jurgen Klopp's first team for pre-season.
"I'm just buzzing and it's a dream come true really to be here," the defender said.
"It was a dream come true to play for Aberdeen, and now to be at one of the biggest, if not the biggest club in the world, it's a massive achievement and I'm looking forward to trying to show the fans what I've got."
The full-back was named young player of the year by the Scottish Football Writers' Association in April after an impressive breakthrough campaign that saw him linked with a host of European clubs.
"There's obviously a pathway here," he said.
"That's one of the reasons I chose it as well. It's not just a massive club, they give young players chances in the first team.
"So if I can come in in pre-season, put my mark down, then there's no reason why I can't push to get in the first-team squad."
