Nations League: What England, Scotland, Wales & Northern Ireland have to play for and impact on World Cup qualifying
All of the home nations have something on the line with two games to go, although the format of the tournament makes that almost inevitable.
Every position above third spot in League C groups guarantees either promotion, relegation, a promotion-relegation play-off or a place in the quarter-finals.
Scotland are close to relegation from League A, sitting bottom by three points before their final games against Croatia and Poland.
England have to beat Greece to have a chance of automatic promotion from League B, or else the best they can achieve is a promotion-relegation play-off with a third-placed team from League A.
Their second game is against the Republic of Ireland, who are three points above Finland and hoping to go into a relegation-promotion play-off.
Wales would win automatic promotion to League A if they beat Turkey and Iceland – but could also be drawn into a relegation-promotion play-off.
Northern Ireland are in an automatic promotion spot in League C and will go up if they win their final two games against Belarus and Luxembourg. They could be promoted with a game to spare if they beat Belarus and Bulgaria do not win.
