Brentford get their second shot at Premier League football after losing the Championship play-off final to Fulham last year. They now face Swansea in "the richest game in football."
The winner is ensured additional revenue of around at least £135 million and up to £265 million over five years, depending on survival in the first Premier League season.
Thanks to parachute payments Swansea's turnover was significantly higher than Brentford's last season, at £50 million to their £13.9 million.
While Brentford recorded a pre-tax loss of £9.1 million, down from a profit of £24.3 million the year before, Swansea turned a £7 million loss into a £2.7 million profit.
