The financial gulf between League One and Championship clubs is forever increasing.
With billion-pound television packages being agreed in the Premier League, broadcast money is slowly making its way down into the second division but stops some way short of reaching the third.
Each Championship side this season will receive a basic payment of £2.3 million, a £4.5m solidarity payment, and are paid between £100,000 and £140,000 for each game selected for live broadcast.
Compare that to the overall payment of just £1.4m a League One side will receive and the £30,000 bonuses for televised games, and it's clear to see just how important promotion is for those near the top of the table.
So, with the English season heading into the final third, Goal brings you all you need to know about the four-team mini tournament that will send one team into the English second division.

When and where is the League One play-off final?
The 2018 League One play-off final is scheduled to take place on Sunday, May 27 at the traditional venue of Wembley Stadium in London.
Kick-off time has been confirmed as 3:00pm BST (10:00am ET).

|Date||Sunday, May 27, 2018|

How can I buy tickets for the League One play-off final?
Both clubs are allocated a set number of tickets for the final and fans can purchase directly from either club, depending on where they wish to be seated.
Last year, prices for adult tickets ranged from £30 up to £80, with concession tickets for children and OAPs are half the price of the standard tickets.
What happened in last year's League One play-offs?
The 2017 League One play-offs were won by Millwall, who subsequently joined Sheffield United and Bolton Wanderers in moving up to the Championship.
The rules of the play-offs dictated that the third-placed team played the sixth-placed team in the semi-finals and the fourth-placed was paired with the fifth-placed team. So Scunthorpe took on Millwall in one semi-final and Bradford played Fleetwood.
Millwall, who beat seventh-placed Southend United to a play-off spot by a single point, beat Scunthorpe over two legs with an aggregate score of 3-2, and would meet Bradford, 1-0 winners over Fleetwood in their semi-final double-header, in the final at Wembley.
The game was settled by a single goal scored by Steve Morison in the 85th minute, securing the Lions' place in the Championship for the 2017-18 campaign.
