Champions League matchday four facts and figures

• Bayern München's 5-1 win over Arsenal was the 13th time the German club have scored five or more goals in a UEFA Champions League match, moving them one ahead of Real Madrid in that particular category and two behind frontrunners Barcelona.

• It was the first time in 165 UEFA Champions League fixtures that Arsenal have conceded five goals. The result also equals the north London team's biggest margin of defeat in the competition – a 4-0 loss at AC Milan in the first leg of the round of 16 in February 2012.

• Zenit maintained their 100% success rate in this season's competition with their 2-0 victory at Lyon. André Villas-Boas's side are one of three clubs guaranteed a round of 16 spot with two games to spare – alongside Real Madrid and Manchester City – but the only one still on course to complete the group stage with maximum points. Only six teams have previously achieved that feat, the most recent being Madrid last term.

• Maccabi Tel-Aviv's 3-1 home reverse to Porto means that, with Shakhtar Donetsk beating Malmö 4-0, the Israeli club are the only one of this season's 32 group stage participants yet to claim a point. The late consolation goal scored by Eran Zahavi did, however, spare them the same fate as their domestic rivals Maccabi Haifa, the sole team in UEFA Champions League history to go through the group stage without registering a point or a goal (2009/10).

• The sending-off of Hernanes in Juventus's 1-1 draw at Borussia Mönchengladbach was the Italian champions' 21st red card in the UEFA Champions League, extending the Turin side's unwanted competition record. The next club in that ranking list is another from Serie A, Internazionale, with 17.

• Thomas Müller's two goals for Bayern against Arsenal lifted his tally in the competition to 32, making him the UEFA Champions League's 13th highest scorer. He is also just two behind Gerd Müller in the all-time European Cup listings, the prolific 1970s Bayern marksman remaining – for now – the highest-scoring German in the history of Europe's premier club competition.

• Galatasaray's 2-1 defeat at Benfica was the Turkish team's 50th in the UEFA Champions League, which matches Olympiacos's total. Only Porto, with 51, have lost more games.

• Barcelona, who overcame BATE Borisov 3-0 at the Camp Nou, and Bayern both earned their eighth successive UEFA Champions League home wins on matchday four. In each case that is just one short of equalling the club record. The competition high for consecutive home victories is held by Manchester United, who posted 12 in a row between September 2006 and April 2008.

• Dynamo Kyiv goalkeeper Olexandr Shovkovskiy is now the third oldest player to have appeared in the UEFA Champions League. He was aged 40 years and 306 days when he faced Chelsea on matchday four. The Ukrainian still has some way to go, however, to rival the record-holder, Marco Ballotta, who was 43 years and 253 days old when he played in Lazio's 3-1 loss against Real Madrid in December 2007.

• Real Madrid's qualification for the next round, thanks to a 1-0 success against Paris Saint-Germain,  means they have never failed to reach the knockout phase in 20 UEFA Champions League participations. It is also their 19th knockout phase appearance in a row, a run stretching back to 1997/98 when they won the trophy. Both feats are competition records.
