Gareth Southgate's England moved to the verge of qualification with a 6-0 win in Bulgaria and will qualify with a draw at home to Montenegro on 14 November, or if Kosovo lose to the Czech Republic on the same night.

Germany will also go through if they draw and Northern Ireland lose.

Scotland's hopes of finishing in the top two are over after a 4-0 thrashing in Russia on Thursday. However, the Scots are guaranteed a play-off place next March thanks to the Nations League.
Belgium became the first team to qualify for Euro 2020 by hammering San Marino 9-0, while Russia joined them with a 5-0 win in Cyprus on Sunday.
