The 2013-14 UEFA Champions League continued with eight matches on Tuesday, November 5.
Groups A-D were in action on the first half of Matchday 5, and there were plenty of highlights.
In the following slides, we recap all the day's action and look ahead to Wednesday's schedule.
Juventus and Real Madrid shared the points in an eventful Group B clash in Turin that featured both sides take—and lose—the lead.
The hosts went ahead via Arturo Vidal's 42nd-minute penalty after Raphael Varane fouled Paul Pogba in the box.
But Real were level within minutes of the restart as Cristiano Ronaldo pounced on a poor back pass, exchanged passes with Karim Benzema and fired past Gianluigi Buffon.
Moments later, Ronaldo's pass set up Gareth Bale, who beat Buffon with a low shot to make it 2-1 in the 60th minute. Within five minutes, Fernando Llorente had headed Juventus level.
With his goal, Ronaldo became the first player to score 14 Champions League goals in a single calendar year. It was his eighth goal of the group stage, tied for the most in the competition's history. He has two matches left to break the record.
The draw sent group leaders Real Madrid up to 10 points. Juventus, still winless in this season's Champions League, are last with three points.
On target: 12-4
Robin van Persie missed a penalty and Marouane Fellaini was sent off as Manchester United sputtered to a scoreless draw at Real Sociedad in Group A.
But while United were left frustrated by missed opportunities, David Moyes' side stayed atop the Group A table with eight points through four matches, one point ahead of Bayer Leverkusen. Real Sociedad are fourth with one point.
Ashley Young drew a penalty for United and van Persie slammed his spot-kick off the post in the 70th minute. Replays suggested Young made the most of the contact, and Twitter exploded in controversy.
Van Persie, a 63rd-minute substitute for Wayne Rooney, also hit the post with a shot from open play in the second half, and Javier Hernandez blasted over the bar from close range following good work from Shinji Kagawa on the left.
On target: 0-2
Alvaro Negredo had a hat-trick and Sergio Aguero scored twice as Manchester City progressed to the knockout stages for the first time with a 5-2 win at home to CSKA Moscow in Group D.
Aguero opened the scoring with a third-minute penalty and doubled City's advantage with a well-taken turn-and-shot 17 minutes later.
Negredo then scored in the 30th, 51st and 90th minutes, in between Seydou Doumbia's double, to seal the win.
The same teams met in Moscow two weeks ago when CSKA fans directed racist chants at Manchester City's Yaya Toure. City's fans showed their support for Toure with an early chant.
Costel Pantilimon again started in goal for City in place of Joe Hart, who has come under criticism for a string of recent mistakes.
On target: 9-6
Substitute Mario Mandzukic scored the only goal as Bayern Munich secured passage to the knockout stage with a 1-0 victory at Viktoria Plzen in Group D.
Bayern have won all four matches so far in the group stage and lead Group D with 12 points. The victory was Bayern's ninth straight in this competition, which is tied for a record.
The hosts largely frustrated Bayern in the final third until Mandzukic broke through with a header in the 65th minute. Bastian Schweinsteiger hit the post with a shot in the first half.
On target: 1-9
Shakhtar Donetsk 0-0 Bayer Leverkusen
The teams played out a scoreless draw in Ukraine. Bayer remained in second place in Group A with seven points.
Shakhtar are third with five.
FC Copenhagen 1-0 Galatasaray
Daniel Braathen scored in the sixth minute to give Copenhagen an unexpected win at home to Galatasaray in Group B.
The result left both teams on four points, six behind leaders Real Madrid and one ahead of Juventus.
Olympiakos 1-0 Benfica
Kostas Manolas' first-half goal was enough to secure three points for Olympiakos in Group C.
The win sent the Greek side clear in second place with seven points, three behind leaders Paris Saint-Germain.
PSG 1-1 Anderlecht
Zlatan Ibrahimovic scored in the 70th minute to end Anderlecht's brief bid for an upset in Group C.
Demy De Zeeuw had given the visitors a shock lead in the 68th minute, but Ibrahimovic leveled for PSG moments later.
Anderlecht's Sacha Kljestan was sent off in the 82nd minute for his second bookable offence.
