Matchday five of the 2017-18 Champions League is set to get under way and we already know some of the teams who will progress from the group stage.
However, there are still a number of places left in the knock-out stage and they may be decided in the upcoming round of fixtures.
Thirty-two teams will be whittled down to 16 for the draw, which takes place shortly after the conclusion of the final group games.
As the composition of the knock-out stage slowly becomes clear, Goal takes a look at everything you need to know.
WHEN IS THE CHAMPIONS LEAGUE LAST 16 DRAW?
The draw for the first round of the Champions League knock-out stage will take place on Monday, December 11 at UEFA’s headquarters in Nyon, Switzerland.
It is scheduled to take place at 11:00 GMT (06:00 ET) and fans will be able to follow it via live stream on UEFA’s official website.
How does the Champions League last 16 draw work?
The draw for the last 16 of the Champions League will be a seeded draw and the winners of the eight groups will be seeded. The eight group runners-up will be unseeded.
Group winners, or seeded teams, will be away for the first-leg matches, which are scheduled for February 13/14 and 20/21, with the second-leg games due to be played on March 6/7 and 13/14.
Teams from the same group or national association cannot be drawn against one another, so, for example, Manchester United cannot be drawn against the likes of Manchester City.
However, that will change for the quarter-final draw, which will be an open draw.
WHAT TEAMS ARE IN THE CHAMPIONS LEAGUE LAST 16?
Ahead of matchday five, only four teams have qualified for the last 16. They are: Paris Saint-Germain, Bayern Munich, Manchester City and Tottenham.
As you can see from the table below, we do not know yet which of those teams will be seeded or unseeded, but that will be confirmed during the course of the final two matchdays, with games concluding on December 6, five days before the draw.

|Group||Seeded||Unseeded||Qualified (Seeding TBC)|
|B||PSG, Bayern Munich|
We know for sure that Celtic and Anderlecht cannot qualify for the last 16, while it is also impossible for Feyenoord. However, many teams – even those with just one point – remain in contention.
What teams are in still contention?
|A||Manchester United, Basel, CSKA Moscow, Benfica||TBC|
|C||Roma, Chelsea, Atletico Madrid, Qarabag||TBC|
|D||Barcelona, Juventus, Sporting, Olympiakos||TBC|
|E||Liverpool, Sevilla, Spartak Moscow, Maribor||TBC|
|F||Shakhtar Donetsk, Napoli||Feyenoord|
|G||Besiktas, Porto, RB Leipzig, Monaco||TBC|
|H||Real Madrid, Borussia Dortmund, APOEL||TBC|
The above table shows the teams that are still in contention to qualify for the knock-out stage of the competition, as well as those who cannot qualify.
A total of 25 teams are vying for the final 12 places in the last 16, but this is likely to decrease dramatically by the end of matchday five.
