With the group stages of the 2016-17 Champions League now done and dusted, attention turns to the last 16 draw, scheduled to take place at Uefa headquarters in Nyon, Switzerland, on Monday 12 December.

Although Tottenham Hotspur have been consigned to another frustrating stint in the Europa League and Celtic eliminated from continental competition altogether, three British teams did make it through to the first knockout phase of Europe's elite club competition. Here, IBTimes UK takes a look at what challenges could lay ahead for the trio of Arsenal, Leicester City and Manchester City in the next round.

Before we do, a reminder that no two teams from the same association can be drawn together at this juncture. The winners and runners-up of the same group will also be kept apart.

Group winners: Arsenal, Napoli, Barcelona, Atletico Madrid, Monaco, Borussia Dortmund, Leicester City, Juventus

Group runners-up: Paris Saint-Germain, Benfica, Manchester City, Bayern Munich, Bayer Leverkusen, Real Madrid, FC Porto, Sevilla

Arsenal/Leicester

Alex Iwobi's own goal against Paris Saint-Germain a fortnight ago left Arsenal facing the familiar prospect of another second-place finish, but they eventually won their group for the first time since 2012 when a 4-1 victory over FC Basel was combined with PSG's shock 2-2 draw against Ludogorets. The Gunners, it is important to note, have been knocked out of the Champions League at the last-16 stage in each of the past six seasons.

Leicester initially took to Champions League football like a duck to water, belying their domestic struggles to concede only one goal in their opening five outings and seal first place in Group G with a game to spare. That gave Claudio Ranieri the opportunity to rest several key players against Porto this week, although such a strategy ultimately backfired as the defending Premier League champions were vanquished 5-0 at the Estadio do Dragao. It was the heaviest margin of defeat for any English club in European Cup history.

Best case scenario: Benfica

Both Arsene Wenger and Ranieri will likely be eyeing Benfica as their favoured next opponents. The reigning Portuguese champions finished second in a notably weak Group B following a 2-1 defeat at home to Napoli.

Porto would also represent a very good draw for Arsenal despite that somewhat misleading final result, while Leicester cannot play them again at this stage. You have to think that neither manager would particularly quibble with being paired against Bayer Leverkusen, either. The Foxes, meanwhile, will be keen to steer clear of PSG.

Worst case scenario: Real Madrid/Bayern Munich

Boasting a seemingly comfortable 2-0 lead over Borussia Dortmund and knowing that they needed to beat the German outfit in order to top Group F, holders and 11-time European champions Real Madrid were stunned on matchday six by two late goals from Pierre-Emerick Aubameyang and Marco Reus. A double-salvo that means Los Blancos unexpectedly head into the last 16 draw as runners-up. Despite that disappointment, the La Liga leaders have now tied Leo Beenhakker's 1988-89 vintage by extending their formidable unbeaten streak to a record-equalling 34 matches.

Having lost 1-0 away to Atletico Madrid in September and also eliminated from last season's semi-finals by the same opponents, Bayern, humiliated by Russian group stage debutants FC Rostov last time out, exacted minor revenge on Los Rojiblancos on Tuesday night as Robert Lewandowski's brilliant free-kick sealed a narrow victory in Bavaria.

Atletico had already sealed top spot before that defeat, however, so Bayern will lurk alongside Real as the most menacing potential match-up for group winners in the last 16. The five-time champions, currently in their first season under Carlo Ancelotti, have reached at least the last four in five successive years. Their domestic supremacy is currently under threat from divisive upstarts RB Leipzig, who currently hold a three-point advantage atop of the Bundesliga thanks to an eight-game winning streak.

Manchester City

City finished second in Group C thanks to David Silva's equaliser against Borussia Monchengladbach and were prevented from providing a winning finish by one of their own players in Celtic loanee Patrick Roberts. Pep Guardiola's troops displayed both sides of their personality against Barcelona, beating the Catalans 3-1 at home after being brushed aside 4-0 at the Nou Camp.

Best case scenario: Monaco

Monaco stand out as perhaps the most favourable draw for City, who are unlikely to face much of an intimidating atmosphere at the quaint Stade Louis II. However, having said that, the principality have forged a reputation as one of the most prolific teams in Europe during the first half of the 2016-17 campaign as they chase a first French title since the turn of the millennium. They beat Tottenham home and away en route to topping Group E, but closed with a disappointing 3-0 defeat to Leverkusen.

If not Monaco, then Napoli would be the tie most City fans will be hoping for. The Serie A outfit failed to win any of the three matches prior to that win over Benfica, gaining just a solitary point against Besiktas and being held to a goalless draw by Dynamo Kiev. A trip to the Stadio San Paolo is not to be relished, although it would be preferable to several of the other potential outcomes.

Worst case scenario: Atletico Madrid

That aforementioned defeat to Bayern stopped beaten 2016 finalists Atletico from finishing their group stage campaign with a 100% record. Before that Lewandowski free-kick, Rostov's Sardar Azmoun was the only player to have breached Diego Simeone's miserly defence in five previous Champions League matches.

Pep Guardiola should be eager to avoid Atletico at all costs and will also not fancy meeting a counter-attacking juggernaut as blistering as Borussia Dortmund. You suspect he would prefer to face Juventus than either of those two sides.
