Lionel Messi scored a hat trick, passing the 200 goals milestone in his Barcelona career and also improving to 42 career Champions League goals (passing Alessandro Del Piero) as Barcelona beat Viktoria Plzen 4-0 while both Arsenal and Chelsea failed to win, home and away.
Chelsea managed only a 1-1 draw in Belgium against Genk, as the Londoners lead through Ramires in the first half, only to play a disastrous final 45 minutes, conceding the equalizer from Jelle Vossen. Valenica got back into qualifying contention with their 3-1 win over Leverkusen with goals from Jonas (fastest goal in the history of the Champions League), Roberto Soldado and Adil Rami.
Arsenal and Marseille still lead the top of the group and finished their game in England with a goalless draw, while Borussia Dortmund got their first win of the campaign, beating Olympiakos with a Kevin Großkreutz goal.
The toughest group to read, and the most surprising so far. APOEL Nicosia grabbed the top spot with a stunning 2-1 win over FC Porto with a dramatic Gustavo Manduca goal in the 90th minute. Zenit beat Shakhtar 1-0 through Nicolas Lombaerts.
Barcelona had no problem in the Czech Republic with Lionel Messi scoring a hat trick and another goal from Cesc Fabregas as they beat Plzen 4-0, while AC Milan struggled in Belarus, finishing their match with BATE Borisov in a 1-1 draw, with goals from Zlatan Ibrahimovic and Renan Bressan.
