uefa.com considers the state of play as Groups A-H conclude, with Arsenal FC aiming to secure their future.
There are nine teams through to the UEFA Champions League first knockout round and another eight places still to be filled. AC Milan, FC Barcelona, PSV Eindhoven, FC Bayern München. Manchester United FC, Juventus FC, Olympique Lyonnais, FC Internazionale Milano and Chelsea FC have already secured their progress and uefa.com considers the possible outcomes as Groups A-H conclude this week.

Leaders Olympiacos CFP need only a point at Liverpool FC to go through, while the English side must win. If Liverpool prevail by a one-goal margin other than 1-0, however, they must hope AS Monaco FC do not beat eliminated RC Deportivo La Coruña; in this case they would lose out to Olympiacos on their head-to-head record. If Monaco win they progress, while if they lose or draw they will go through if Liverpool do not win. Should Monaco draw and Liverpool win, the English side are through and so are Olympiacos, unless they lose by a margin of three or more in which case Monaco will advance. Deportivo will finish last whatever happens, with the third-placed side entering the UEFA Cup.
Only one issue is settled: AS Roma will end in fourth. Dynamo are two points clear of Real Madrid CF and Bayer 04 Leverkusen, and the Ukrainians can qualify with a point in Germany. Madrid will be through if they win in Rome, but should they draw they must hope Leverkusen lose against Dynamo, otherwise the Spaniards will instead enter the UEFA Cup. A Roma win would ensure Leverkusen and Dynamo both progress.
Juventus and Bayern will claim the top two places in that order. AFC Ajax will finish third ahead of Maccabi Tel-Aviv FC as long as they do as well against Bayern as the Israeli club do against Juventus.
United and Lyon are through. Lyon will finish top only if they beat bottom side AC Sparta Praha and United fail to win at Fenerbahçe SK, who are confirmed UEFA Cup entrants.
PSV have ensured progress past this stage for the first time in nine attempts, and require just a draw at Panathinaikos FC to finish top. Arsenal FC are second, a point above Panathinaikos, and a home win against Rosenborg BK will see them through - and into first place if PSV lose. Panathinaikos must defeat PSV and hope Arsenal fail to win, with the lower-placed of the English and Greek title-holders entering the UEFA Cup. Rosenborg will finish fourth.
Milan and Barcelona have advanced, with the Italian champions two points ahead. Milan can only be denied first place if they lose at Celtic FC and Barcelona defeat bottom side FC Shakhtar Donestk. Shakhtar must gain more points at home to Barcelona than Celtic do against Milan to pip the Scottish champions to the UEFA Cup.
Which club joins Inter in qualifying will be decided in Spain, where Valencia CF must defeat Werder Bremen either 1-0 or by a two-goal margin to go through instead of the German champions. Whoever does not succeed at the Mestalla will go into the UEFA Cup - which Valencia won last season - with RSC Anderlecht unable to rise from fourth place.
Chelsea will finish first. Paris Saint-Germain FC lie second and will advance with a home win against PFC CSKA Mosvka. Otherwise, holders FC Porto can progress with a win against visitors Chelsea. If Porto draw or lose, CSKA will advance with a win while PSG would require just a draw. Should Porto not better PSG's result they will enter the UEFA Cup, otherwise the French team will end up third, except if Porto and CSKA win, in which case the Russian side will enter that tournament.
