Leeds United only have two players out of contract at the end of the season, although they do have Weston McKennie's future to decide on.
McKennie joined the Whites on loan until the end of the season from Juventus in January, and have an option to make the deal permanent in the summer.
The American is set to cost £34.3 million, although a permanent deal will is likely to depend on many factors, including if Leeds are still in the Premier League, and who will be in the dugout next season.
