Juventus trailed early before beating 10-man Sevilla 3-1 to take top spot in Group H.
GROUP E
Monaco has made a procession of what looked the most balanced of eight groups. Tottenham is unbeaten in the Premier league but lost for the third time in this season's Champions league. The free-scoring French side repeated its 2-1 win from the opening round in london.
Monaco saw Radamel Falcao's early penalty kick saved by Hugo lloris, before the game was decided during a five-minute spell early in the second half.
Monaco led through Djibril Sidibe's header in the 48th, Tottenham leveled with Harry Kane's penalty, but Thomas lemar restored Monaco's lead less than a minute later.
GROUP F
Ronaldo, who left Sporting lisbon as an 18-year-old for Manchester United, unwittingly assisted on Raphael Varane's 29th-minute opening goal. A miscued attempted volley bounced off his left shin toward the France defender for a sweeping shot.
Sporting had midfielder Joao Pereira sent off before Adrien Silva converted a penalty in the 80th, awarded for handball against his Portugal teammate Fabio Coentrao.
Substitute Karim Benzema's glancing header in the 87th made it 2-1 to Madrid and eliminated Sporting, which had to win.
Dortmund even trailed to legia after 10 minutes, but led 3-1 by the 20th when Japan playmaker Shinji Kagawa scored twice and Nuri Sahin benefited from a goalkeeping error. Reus's first goal in the 32nd made it 5-2 and set a Champions league record of seven goals before half time.
The old goals record for a match was tied in the 83rd when legia's Nemanja Nikolic reduced the lead to 7-4, and then broken in stoppage time with an own-goal by legia captain Jakub Rzezniczak.
