While Manchester United’s 2-1 win over CSKA Moscow in Group A confirmed top spot for Jose Mourinho’s men, Chelsea’s 1-1 draw at home to Atletico Madrid on Tuesday proved costly.

The result means that Antonio Conte’s team surrendered top spot in Group C to Roma and could now face a daunting prospect in the knockout stages.

Here, we take a look at their potential opponents, those of fellow Premier League sides Manchester City, Tottenham and Liverpool (all of whom are confirmed as group winners)

Group winners will face runners-up
One of the advantages of winning your Champions League group is that this guarantees that a team will not have to play one of the other seven sides who topped their group too. So United, City, Liverpool and Spurs know they will be up against teams who finished second.

The four teams to have secured second spot on Tuesday were Basel, Bayern Munich, Chelsea and Juventus. Real Madrid were also confirmed to finish second and have been joined by three more sides – Sevilla, Shakhtar Donetsk and FC Porto.

Are there any other restrictions?

In the round of 16, teams cannot be drawn against sides who they faced in the group stages. That means Chelsea cannot draw Roma, Manchester United cannot be drawn to play against Basel, and Tottenham will not be up against their Group H opponents Real Madrid.

It is also not possible for teams from the same country to be drawn against each other in this round.

With Liverpool securing top spot, that makes things even trickier for Chelsea. As a result of these restrictions, the Blues are only able to draw three teams in the round of 16 – Barcelona, Paris Saint-Germain or Besiktas.

The possibilities

Chelsea: Barcelona, Paris Saint-Germain, Besiktas

Manchester United: Bayern Munich, Juventus, Real Madrid, Sevilla, Shakhtar Donetsk, Porto.

Manchester City: Bayern Munich, Juventus, Basel, Real Madrid, Sevilla, Porto.

Tottenham: Bayern Munich, Juventus, Basel, Sevilla, Shakhtar Donetsk, Porto.

Liverpool: Bayern Munich, Juventus, Basel, Real Madrid, Shakhtar Donetsk, Porto.

Anything else you need to know?

These restrictions are removed ahead of the quarter-finals. From that point onwards, it is a free draw so group-stage rematches and any all-Premier League clashes could be back on the agenda.

When is the draw and when are the games?

The draw for the round of 16 takes place at UEFA’s headquarters in Nyon in Switzerland on Monday. The first legs will be played on 13/14, 20/21 February, and the second legs will be played on 6/7, 13/14 March 2018.
