Who Makes the Round of 16 of the Champions League? All You Need to Know!

The opening few rounds of the Champions League were light and breezy, but now, teams are consistently looking at their chances and goal differences to ascertain how they could make it to the Round of 16.
The UEFA Champions League group stages offered exciting action from the opening game and also brought in a few upsets.
Defending champions Manchester City and RB Leipzig have become the first teams to secure their spots in the Champions League knockout stages, reaching the last 16 with two matches to spare.
Last week, Bayern Munich, Inter Milan, Real Madrid, and Real Sociedad joined them.
So where to from here? Who will fill in the following spots?
Group A has had the most excitement in the Champions League, and most of it involves Manchester United. The 4-3 loss to Bayern Munich was disappointing, but it showed that United was a challenging side. It was a blast for many who purchased tickets for the United vs. Bayern game through trusted resellers such as Seatsnet.
With seven goals scored between the two sides, the team was looking to finish in the top 2.
But all that went down when United lost to Galatasaray and FC Copenhagen.
Bayern Munich has already qualified for the Round of 16 after their win against Galatasaray. Manchester United, FC Copenhagen, and Galatasaray can reach the last 16.
But United's fate is quite tricky. If FC Copenhagen also records two victories, they may need to win more than two matches in their final two. This would mean that they will need help from their other teams to hand in defeats so that United's points will make them easily qualify automatically.
However, the outset is not favoring the Red Devils.
The next match against Galatasaray on November 29 is crucial for United.
Arsenal, who are returning to the UEFA Champions League, will easily make it to the next Round from Group B. They've been the dominant force in the group, and fans with tickets from reseller Seatsnet also denote that they love Arteta's approach to Europe.
Arsenal will secure advancement as Group winners if they defeat Lens at home on November 29 or even avoid defeat. Their promotion could be confirmed before their match if Sevilla beats PSV Eindhoven in the earlier fixture on the same day.
The Gunners, PSV, Lens, and Sevilla still have an open spot to make the knockout stages.
For the team that has had exceptional success in the Champions League, Real Madrid made it to the knockout stages for the 26th successive season with a win against Sporting Braga. While Real Madrid secured advancement, Napoli, Sporting Braga, and Union Berlin are still mathematically in contention.
Qualification will be challenging for Napoli, the defending Italian Serie A champions. They must defeat Madrid later in the month to make it happen.
In Group D, Real Sociedad and Inter Milan secured their positions in the Champions League knockout stages. Last season's semifinalists, Inter Milan, are making it count again in European competition.
The influx of new players in the summer transfer window has helped them stay afloat and increase ticket sales, according to Seatsnet (trusted retailer platform).
The final two rounds in the qualifiers will decide the teams for the remaining spot. The contest is between RB Salzburg and Benfica, who are also eyeing the Europa League play-off spot.
Group E has Atletico Madrid on top with seven points. But Atletico needs more time to relax with Lazio, who also has seven points.
Both teams are looking for their qualification ticket. For Madrid, the equation is simple: win or draw; you'll qualify.
For Lazio, it will be a win to qualify.
Celtic has had a tough group stage run this year. They've stayed within the Champions League group stage since the 2012-13 season.
And for them to advance is impossible.
Theoretically, they must win the remaining games against Feyenoord and Lazio and score at least two goals in their away fixture against Lazio.
Additionally, Celtic's hopes rest on both opponents, where they anticipate Feyenoord and Lazio to lose to Atletico Madrid.
Surprisingly, Celtic is the only side currently in the elimination zone in Group E, whereas all the other teams are still fighting for the Round of 16 spot.
Despite the massive win against PSG at home, Newcastle United might not make the Round of 16.
Borussia Dortmund">Borussia Dortmund has topped its group after playing four games, winning two, drawing one, and losing one. With seven points, they are above PSG, which has six, including two losses.
For Newcastle to qualify, they must defeat PSG at home in the next matchday. If they succeed, they will take second place with one game.
The UEFA Champions League defending champions and treble winners, Manchester City, maintain their perfect record in the group stage, collecting all the points on offer from their four games.
Manchester City secured a spot in the last 16 with two matches in hand after a victorious encounter against Young Boys. In parallel, their group rival secured their knockout seat when they won against Red Star Belgrade to finish at 9 points with two games in hand.
City can clinch the top spot in the group with a game to spare if they avoid defeat against Leipzig in their upcoming fixture at Etihad Stadium on 28 November.
Group H has Barcelona and FC Porto tied at 9 points.
Barca suffered a setback when they failed to get a point against Shakhtar Donetsk and faced defeat. But the five-time winners can advance with a game in hand if they register a win against FC Porto on the next match day.
Porto and Shakhtar, set to clash on matchday six, are still vying for qualification.
While Royal Antwerp's aspirations have dimmed, the Belgian champions could land in the Europa League if they win their final two games and Shakhtar faces defeat.
