Leeds, Derby, West Brom and Aston Villa are set to battle it out for a place in next season's Premier League.
The four clubs are looking to become the third team to win promotion from the Championship - but have to do it via the play-offs.
Norwich City won the league ahead of Sheffield United, with both clubs securing their place in the top tier for next season in the process.
And if anyone else wants to join them, they have to do it the hard way.
Leeds had secured their place in the play-offs following a successful campaign which saw them just fall short of Sheffield United in the closing stages.
