The scramble for Euro 2020 places comes to its conclusion this week as the final international fixtures of the year are played out across the continent.
Six countries have already secured their spot at next summer's finals and several others stand on the brink. For some, however, it's going to be a nervous few days.
We pick out 10 things to keep a close eye on during this decisive round of internationals.

CAN WORLD CHAMPIONS FRANCE SECURE TOP SEED STATUS?
The seedings for next summer's finals draw will be determined by group position and, as it stands, there are a few big fish lurking in pot two for when the draw takes place in Bucharest on November 30.
Reigning world champions France are currently second in qualifying Group H and if that were to remain the same, they could be paired with the likes of England, Spain or Holland in a Euro 2020 group.

France are currently tied on 19 points with group leaders Turkey and sit second by virtue of an inferior head-to-head record against the Turks.
In order to clinch top spot, Les Bleus may have to win both their remaining games, at home to Moldova on Thursday and away to Albania on Sunday, and hope Turkey drop points in their games with Iceland and Andorra.
A win over Moldova in Paris on Thursday will secure France's automatic qualification in any case, while Turkey need only a draw against Iceland to book their place at the finals.

COULD HOLDERS PORTUGAL REALLY MISS OUT?
Portugal are the reigning European champions after their win over France back in 2016 and they also won the inaugural UEFA Nations League on home turf back in the summer.
But there is a possibility that Cristiano Ronaldo and Co may be absent from next summer's finals as they face a nervy could of games this week.
Ukraine's win over Portugal last time out took them through as Group B winners, leaving Portugal second on 11 points and Serbia third on 10.

It means Portugal need to take maximum points from their home game against Lithuania on Thursday and Sunday's trip to Luxembourg to settle automatic qualification.
Any slips and it could be the play-offs in March to earn the right to defend their crown.

HOLLAND AND GERMANY SLUG IT OUT FOR TOP SPOT
It's been nip and tuck between old rivals Holland and Germany for first place in Group C, with the Dutch currently top by virtue of a better head-to-head goal difference.
The priority of both remains to secure qualification with Northern Ireland snapping at their heels (more on them later).

Holland head to Belfast on Saturday knowing they will get through with a draw, while Germany will make it if they beat Belarus and Northern Ireland fail to beat Holland.
But both Holland and Germany will fancy finishing top of the group because this should theoretically secure an easier draw for next summer's finals.

BUT CAN NORTHERN IRELAND PIP THEM?
It was always an absolute killer of a draw for Northern Ireland, but they've done themselves proud and are still in with a shout of repeating their 2016 Euro qualification.
They won their first four matches in the group before losing to Germany and then agonisingly to Holland having led with 10 minutes to play in Rotterdam.

In truth, they'll need to beat both again in their final two fixtures - against Holland in Belfast on Saturday and Germany in Frankfurt on Tuesday - to steal into the top two.
But, as it stands, they will take a play-off place and therefore all hope of reaching another finals isn't lost yet for the Green and
