Midfielder Joe Williams has joined Barnsley on a season-long loan.
The 20-year-old will gain Football League experience by spending the 2017/18 campaign in the Championship with the Tykes.
Williams, who has been with the Blues since the age of seven, moves to Oakwell after helping Everton Under-23s win the Premier League 2 title last season.
He missed the majority of the 2016/17 campaign with knee and ankle injuries but regained full fitness in February and was named on the bench by Ronald Koeman for a handful of Premier League matches without being called upon.
