Eight places in the Champions League's last 16 are still up for grabs heading into the last round of group games. Three traditional heavyweights - Barcelona, Real Madrid and Bayern Munich - are already through, as are former champion Chelsea, Paris Saint-Germain and Manchester City. Tottenham and Beşiktaş complete the set of current qualifiers.
Atletico Madrid needs a lot to happen to keep alive its streak of four consecutive appearances in the knockout stage. Diego Simeone's team must beat Chelsea away and needs Roma to draw or lose against Azerbaijani team Qarabag at home. Atletico didn't win any of its first four matches in Group C. Sevilla is in a much more comfortable position as it can reach the last 16 for the second straight season with a draw at Maribor on Wednesday. Sevilla can win Group E with a win if Liverpool fails to defeat Spartak Moscow at home.
England is already assured of having two group winners in the last 16, through Manchester City and Tottenham. By Wednesday, it could have five. Today, Manchester United needs just a point at home to CSKA Moscow to seal first place in Group A, and already qualified Chelsea can finish top of Group C by beating Atletico. A day later, Liverpool can secure top spot in Group E by beating Spartak.
Germany's representation in the last 16 could come down to just one team, Bayern Munich, after disappointing campaigns from the Bundesliga's best - Borussia Dortmund in particular. Dortmund is already out after failing to win any of its group games and is now competing with APOEL for the consolation of Europa League qualification from Group H. Ahead of its visit to Real Madrid on Wednesday, Dortmund has just two points from five games, the same as Cypriot team APOEL. Leipzig still has a chance to progress on its European debut but needs a favor from Monaco at Porto in Group G. Leipzig, which is level on points with Porto, hosts group winner Beşiktaş on Wednesday and will only go through if it secures more points than the Portuguese team. Bayern hosts Paris Saint-Germain on Tuesday needing to win by a four-goal margin to progress as Group B winner. PSG beat Bayern 3-0 in Paris and has a far superior goal difference. Germany's fourth team, Hoffenheim, didn't make the group stage after losing in the playoffs to Liverpool.
None of the three Italian clubs in the competition have advanced yet. Napoli appears to have the toughest path to the knockout stage. The Partenopei must win at Feyenoord on Wednesday and hope Manchester City beats Shakhtar Donetsk in Group F. Juventus can go through with a win at Olympiakos in Group D today or if Sporting Lisbon fails to beat Barcelona. Roma can also go through with a win against Qarabag in Group C today, or if Atletico Madrid fails to beat Chelsea. PSG is seeking a sixth straight group win and to rebound from a shock 2-1 loss to promoted Strasbourg in the French league.
