Match-day five of the 2011/12 Champions League season is now complete with a few more teams progressing through to the Round of 16.
In Group E, Chelsea lost 2-1 in Germany to Bayer Leverkusen after taking the lead and will need a goalless or draw or a win over Valencia on match-day six to qualify. Didier Drogba opened it up for the Blues but Bayer responded in the 73rd minute through Eren Derdiyok before Manuel Friedrich grabbed an injury-time winner to send his side to the top of the group ahead of Valencia who produced their biggest-ever Champions League win and biggest by a Spanish club by beating Genk 7-0 thanks to a Roberto Soldado hat-trick.
Group F saw Olympiakos climb off the bottom of the table with a 1-0 away win at Marseille and the Greek club now have to beat Arsenal and hope Marseille don't win against Borussia Dortmund to qualify. Arsenal topped the group with a 2-1 home win over Dortmund thanks to Robin van Persie's double to make it 38 in 41 outings in 2011. The German club can still qualify if they beat Marseille and Arsenal beat Olympiakos in the final group matches.
There was history in St Petersburg with APOEL Nicosia becoming the first Cypriot side to qualify for the Champions League Round of 16 thanks to a 0-0 draw against Zenit. The Russians will now have to successfully navigate FC Porto on match-day six to win second spot after the Portuguese outfit beat Shakhtar Donetsk 2-0 with the Ukrainians enduring their worst-ever run in the competition of seven without victory.
And in Group H, Barcelona finished on top of AC Milan thanks to their 3-2 win at the San Siro. Mark van Bommel's own-goal put Barca ahead before Zlatan Ibrahimovic made it four in four in the group stage to level against his former club. Lionels Messi converted from the penalty spot on the half-hour mark to restore the visitors' lead before Kevin-Prince Boateng again equalised for the Rossoneri before Xavi grabbed a winner for Blaugrana just after the hour-mark. In the other match, Czech outfit Viktoria Plzen got their first Champions League win with a 1-0 result at BATE Borisov.
