A look at the worst possible Champions League draws England's remaining teams could land.
The Champions League draw takes place this Monday, and teams will be keen to learn their fate.
We have looked at the possibilities for each team, and the worst case scenarios they will be desperate to avoid...
Possibilities: Real Madrid, Bayern Munich, Barcelona, Porto, Atletico Madrid, Monaco.
The worst team the Gunners could face in the knockout rounds is Bayern Munich. The German champions have been drawn with the Gunners in the last 16 for the past two seasons, and it would be a sickener for Arsenal if it were to happen again. Pep Guardiola's side fell short last season at the semi-finals, and are determined to win it this time around. In the Bundesliga this season, Bayern's record is Played 15; Won 12; Drawn 3; Lost 0.
Real Madrid, Barcelona and Atletico Madrid are all teams the Gunners will feel wary of, but a clash with either Porto or particularly Monaco would feel winnable.
Possibilities: Bayer Leverkusen, PSG, Juventus, Basel, Shakhtar Donetsk.
The worst possible draw for Chelsea would involve being reunited with PSG. The two teams played a tough knockout encounter last season, with Jose Mourinho's side losing the first leg in Paris. The French champions beat Barcelona earlier this season there too, and will be keen to show they can take the next step. Juventus would be another tough draw, a team Chelsea won't have fond memories of - but they have looked like they lack belief in Europe so far this season.
An ideal draw would be against Bayer Leverkusen, who are 15 points off leaders Bayern in the Bundesliga, with trips to Shakhtar and Basel tricky but winnable. Every team they could draw, will be just as fearful if not more so of Chelsea.
Possibilities: Real Madrid, Barcelona, Atletico Madrid, Porto, Borussia Dortmund, Monaco.
The worst draw for City, would just like Arsenal and Chelsea - be a repeat of a game they played in previous years, against Barcelona. While Luis Enrique is still working to put his stamp on the side, could you really back against the trio of Lionel Messi, Luis Suarez and Neymar scoring away goals? Real Madrid would be a particularly unwanted draw too, while Atletico Madrid or Borussia Dortmund would present real problems.
City should be hoping they can draw Porto, who they beat heavily in the Europa League a couple of seasons ago, or Monaco, who surprised many by topping their group.
