BBC Sport outlines the battles for promotion and relegation - and all the European qualifiers - in England and Scotland.
RECENT PROMOTIONS AND RELEGATIONS
Leicester City were crowned Premier League champions on 2 May without kicking a ball after Tottenham failed to beat Chelsea. They will be joined in the Champions League group stage by runners-up Arsenal and third-placed Tottenham. Meanwhile, Manchester City finished fourth, meaning they will be in the Champions League play-off round. The Europa League place City earned from winning the Capital One Cup transfers to the league.
FA Cup winners Manchester United, who finished fifth, will enter the Europa League group stages along with sixth-placed Southampton, while seventh-placed West Ham United enter at the third qualifying round, courtesy of United's FA Cup win.
There are no longer any Fair Play places allocated to the Europa League.
