( CNN ) -- Cristiano Ronaldo warmed up for Saturday 's El Clasico by firing Real Madrid to victory over Juventus in the European Champions League . Ronaldo scored twice as Real defeated the Italian champion 2-1 at the Bernabeu to make it three wins out of three in Group B . The Portuguese star has now scored seven goals in this season 's competition , netting either side of a Fernando Llorente strike to seal the points . `` We have taken a very important step towards securing qualification , '' Real captain Iker Casillas told reporters . `` It was n't easy but we have taken the first step , getting nine points from three matches . We have to go to Turin now and at least avoid defeat . '' Juventus now finds itself in danger of being eliminated at the Group Stage after taking just two points from its opening three games . Its case was not helped by Turkish side Galatasaray , which defeated FC Copenhagen 3-1 to move up to second in the group . Real , which is currently third in La Liga , will now travel to Barcelona with the mission of inflicting a first league defeat of the season on its arch rival . Coach Carlo Ancelotti could even give $ 138 million signing Gareth Bale a place in the team after the Wales international made a cameo appearance as a substitute following his recovery from a thigh injury . `` He came on when the match has lost its intensity , '' Ancelotti said at a news conference . `` That did n't help him play better but it was important for him to get some time on the pitch , '' added the Italian . `` I think now he is ready to start a match . '' While Ronaldo stole the show in the Spanish capital , it was Zlatan Ibrahimovic who lit up Brussels with a four-goal salvo . The Swede , who is set to come up against Ronaldo in the World Cup playoff , scored a hat-trick inside 19 minutes as Paris Saint-Germain crushed Anderlecht 5-0 . Ibrahimovic added a fourth on 62 minutes to take his tally to nine in his past four appearances . Edinson Cavani added a fifth as PSG underlined its credentials as serious challengers . `` It was a really good game with plenty of positives all over the pitch . It was the perfect match , '' declared PSG coach Laurent Blanc . `` Ibrahimovic 's four goals were exceptional . It is difficult to say which was the best . `` Winning the Champions League would be a dream for all the players and the board . But it is a difficult objective . `` We need to go one step at a time and the first is to win the group . '' PSG sit top of Group C with maximum points -- five ahead of Olympiakos which was held to a 1-1 draw at Benfica . Defending champion Bayern Munich eased to a 5-0 win over Czech side Viktoria Plzen to maintain its perfect start to the competition . Franck Ribery scored twice , while there were also goals for David Alaba , Bastian Schweinsteiger and Mario Gotze . `` I am happy with the performance of the players , '' Bayern boss Pep Guardiola told reporters . `` I believe that in the European matches this season , including the Super Cup win over Chelsea , we have played well but in the Bundesliga it has taken us longer to click into gear and perhaps we need more time . '' Bayern has taken nine points from nine and sits top of Group D with Manchester City in second place . Sergio Aguero scored twice as City won 2-1 at CSKA Moscow in a game which was marred by racist chanting . City midfielder Yaya Toure was subjected to `` monkey chants '' by home supporters and the club will now take up the matter with UEFA , the European game 's governing body . Manchester United claimed a vital 1-0 win over Real Sociedad at Old Trafford thanks an own goal by Inigo Martinez . The home side wasted several other chances to increase their lead while the visiting side struck the crossbar through Antoine Griezmann . `` I thought we played well tonight . I thought we created opportunities , '' said United manager David Moyes , whose side was held to a 1-1 draw by Southampton in the Premier League last weekend . `` But while it was 1-0 , I still had feelings of Saturday left inside me and while it was 1-0 , you know you can always lose a goal from a corner kick or a free-kick . `` But it would n't have been right if we had n't taken all three points tonight . '' United is one point clear at the top of Group A following Bayer Leverkusen 's 4-0 home win over Shakhtar Donetsk . Stefan Kiessling scored twice with Simon Rolfes and Sidney Sam also on target for the German side .
