Barnsley have signed Liverpool midfielder Herbie Kane for £1.25m on a four-year contract.
The Premier League champions will retain a 15% sell-on clause for the 21-year-old, whose only first-team games were in last season's Carabao Cup.
Leicester City midfielder Matty James, 29, has also rejoined the Tykes for a second loan spell until January.
Meanwhile, striker Cauley Woodrow has extended his deal with the club until the end of the 2022-23 season.
Woodrow, 25, has scored 31 goals in 74 league appearances since initially joining on loan from Fulham in August 2018.
He had been linked with a possible move to Championship rivals Cardiff City.
