For the first time in three years, Manchester United find themselves waiting to learn their fate for the knock-out stages of the Uefa Champions League. Jose Mourinho's side made light work of their group campaign, securing 15 points from a possible 18 with Romelu Lukaku and Marcus Rashford applying the gloss against CSKA Moscow on Tuesday.

Things could be about to get a little tougher, however. Qualifying as group winner typically sees you avoid the best the competition as to offer. Not so much this year. IBTimes UK considers the best and worst scenarios awaiting United.

When and where is the last-16 draw?

The draw begins at 12:00CET on Monday 11 December and will take place at the Uefa headquarters in Nyon [Switzerland].

Teams Manchester United can draw in Champions League last 16: Bayern Munich, Juventus, Real Madrid, Sevilla/Spartak Moscow, Shakhtar Donetsk/Napoli, Porto/RB Leipzig

Group winners: Manchester United, Paris Saint-Germain, AS Roma, Barcelona, Manchester City, Besiktas, Tottenham Hotspur, Liverpool

Group runners up: Basel, Bayern Munich, Chelsea, Juventus, Sevilla, Shakhtar Donetsk, FC Porto, Real Madrid

Worst possible scenario for United: Real Madrid?

They may be eight points off the top in Spain and may have been humbled by Tottenham Hotspur in the group stages, but a meeting against the defending champions at the last 16 stage must surely be considered one to avoid. United and Real met as recently as August in the Uefa Super Cup where Zinedine Zidane's side, inspired that evening by sublime Isco, comfortably outclassed their Premier League opposition despite Romelu Lukaku's consolation goal.

The two were paired at this stage of the competition in what was Sir Alex Ferguson's last ever Champions League tie in 2013 – one made memorable for the red card shown to Nani which led to the side then managed by one Jose Mourinho eliminating the Manchester club.

A loss at Wembley and their failure to beat Tottenham at the Bernabeu ultimately cost Real top spot in their group. Italy and Germany's best suffered a similar fate with Juventus and Bayern Munich also finishing second behind Barcelona and Paris Saint-Germain respectively. They also lie in wait.

Best possible scenario for United: Porto

Another of Mourinho's former clubs possibly looms large. Porto clinched second place in Group G ahead of competition debutants RB Leizpig after Besiktas' stunning campaign saw them rise to the summit. Benfica's miserable campaign that saw them finish bottom of United's group without a point to their name shouldn't reflect the standing of Portuguese clubs in this competition but a tie with the side the United manager led to the 2004 title represents, on paper at least, the best possible option at this stage.
