Champions League will feature the first eight matches of the last sixth round tonight.
"EuroFootball.com" looked at the situation of teams in the standings and what results they will seek on Tuesday.
Group A:
London's "Tottenham" and Milan's "Inter" have already secured their places in the knockout stages, so the only question in this group is which team will take first place and which one will take second.
The English club, traveling to Enschede's "Twente," only needs to achieve a result not worse than Bremen does against the struggling "Werder" to surpass the Milanese.
Although "Tottenham" will be without the injured leader Rafael van der Vaart, "Inter" also has no reason to harbor great ambitions, as they are far from displaying the best game - they lost to Rome's "Lazio" in the Italian championship on Friday.
Group B:
A similar situation in this group - Schalke" and "Lyon" are sure to advance to the next stage. However, the fate of the first place is not yet precisely clear - the Germans currently have a one-point advantage and will face Lisbon's "Benfica," who should be motivated by the fact that a loss could take the third place away from the Portuguese and a consolation prize ticket to the Europa League.
"Lyon" will play at home against Tel Aviv's "Hapoel." The Jews still nurture hopes of making it to the Europa League, but for that, they need a victory against the French and a "Schalke" win against "Benfica."
Group C:
There are no big unknowns in Group C - "Man Utd" and "Valencia" are already waiting for the knockout stages. The Spaniards still have hopes of taking the first place if they win in England, but coach Unay Emery insists they won't be too aggressive.
Meanwhile, "Man Utd" can achieve a new league record - so far, in five group stage matches, Sir Alex Ferguson's players have not conceded a goal.
In the Europa League, from this group will be Glasgow's "Rangers," while "Bursaspor" will try to win at least one point in the last match.
Group D:
The intrigue is alive in Group D - although "Barcelona" has already secured the first place, "Kobenhavn" and Kazan's "Rubin" still have something to fight for.
Currently, the Danes are in second place with 7 points, but the Russians, having one point less, have not given up hope of breaking through among the top 16 European clubs.
"Rubin" will travel to Barcelona, hoping that coach Pep Guardiola's words about "difficult to find motivation" for this match will come true, and the "Kobenhavn" club will seek to settle everything at home by defeating the last-placed Athens' "Panathinaikos." A victory for the Danish team would allow them to relax and not look at the result heading to Catalonia.
