Bayern Munich and Real Madrid produced dominant performances in the Champions League as the likes of Arjen Robben and Cristiano Ronaldo found the net on a good night for Europe's top forwards.
Robben helped Bayern outclass Manchester City 3-1 away, a demonstration that Bayern's defense of the title is right on track with two wins from two games.
"We controlled the match and that is important in the Champions League," Bayern's coach Pep Guardiola said.
Ronaldo and Angel Di Maria scored two goals each for Real Madrid in a 4-0 rout of Copenhagen, while Zlatan Ibrahimovic notched a brace for Paris Saint-Germain in a 3-0 demolition of Benfica.
They were all outdone by Kostas Mitroglou, who scored a hat trick to lead Olympiakos to a 3-0 victory at Anderlecht. Manchester United was held to a 1-1 draw at Shakhtar Donetsk, while City's former coach Roberto Mancini steered Galatasaray to a 2-2 draw at Juventus, just two days after taking charge of the Turkish side.
Ronaldo's two goals against Copenhagen raised his total for two games to five, following a hat trick in a 6-1 win at Galatasaray on the opening matchday.
Madrid coach Carlo Ancelotti said he was pleased with the game, saying it had a good beginning, intensity and balance.
"We tried to carry on scoring right into the last minutes, there was a good attitude in the team."
Copenhagen coach Stale Solbakken praised Ronaldo, saying: "He is the man of the match with his two goals."
With 10 goals in two matches and six points Real is firmly in control of Group B, ahead of Juventus with two points.
Juventus nearly picked up all three points on the night when substitute Fabio Quagliarella made it 2-1 with an 87th minute header -- only for Didier Drogba, who had earlier put the Turkish side in front, to find Umut Bulut for an immediate equaliser.
Bayern also has a perfect record at the top of Group D, while CSKA Moscow pulled level with City on three points with a 3-2 victory over Viktoria Plzen, with Zoran Tosic scoring one goal and setting up another.
