This week, EFL sides all do battle for a place in the Premier League – and it's straight knockout football.
It's a curious thing, the play-offs. After 46 matches, your season can come down to three games, and whether you finished sixth after a late surge or you slipped out of the top two on the final day of the season, you can still make it to the big time.
Form won't matter this week, either. This is the biggest game in football, financially speaking, and there are often shocks at this stage of the competition. It really could go any way, as the cliche goes.
Who's your money on? For now, we're just looking back at everyone to have benefitted from this lottery, from the Championship down to League Two.
