Frenchman Franck Ribery scored a brace, including one from the penalty spot, while David Alaba, Bastian Schweinsteiger and Mario Goetze were also on target as Pep Guardiola's Bayern romped to a 5-0 home win against Czech champions Viktoria Pilsen, their eighth consecutive win in the competition. The German outfit are three points clear at the top of Group D from Manchester City, the Premier League club who claimed a potentially crucial 2-1 win at CSKA Moscow earlier in the day. City had fallen behind on a difficult pitch at the Arena Khimki when Zoran Tosic lobbed Joe Hart, but Sergio Aguero netted twice before the interval to turn the game on its head. "It is an important win," City manager Manuel Pellegrini said after the game. Now we have to play the next two games at home. I told the players that we had to make sure we didn't lose this one. We are not in the next round yet but this was an important step. PSG recorded their biggest European away win as they took Anderlecht apart in Brussels, Zlatan Ibrahimovic scoring four times and Edinson Cavani once in a 5-0 victory. Ibrahimovic's evening featured a hat-trick in the space of 19 first-half minutes, with his third goal a ferocious volley from 30 yards that brought many of the home supporters to their feet. And he now has nine goals in his last four games in all competitions. With Oscar Cardozo's late equaliser earning Benfica a 1-1 draw at home against Olympiakos in the group's other game, PSG are now five points clear at the top and in a position to clinch qualification when they meet Anderlecht at home next. Despite Ibrahimovic's feats, the competition's top scorer is Cristiano Ronaldo, who took his tally for the season to seven with a brace in Real Madrid's 2-1 win against Juventus at the Santiago Bernabeu. Ronaldo opened the scoring in the fourth minute and then scored what proved to be the winner just before the half-hour mark following an equaliser by Juve's Spain striker Fernando Llorente. Carlo Ancelotti's side have a maximum nine points from three games in Group B, while Juve are still without a win and lose second place to Galatasaray, for whom Felipe Melo, Wesley Sneijder and Didier Drogba all scored in a 3-1 victory over FC Copenhagen. Meanwhile, Manchester United remain in control of Group A, if only just, after a second-minute own-goal by Inigo Martinez gave them a 1-0 home win against Real Sociedad at Old Trafford. United are a point clear of Bayer Leverkusen, who leapfrogged Shakhtar Donetsk into second place by beating the Ukrainians 4-0 in Germany. Stefan Kiessling made headlines at the weekend with his now infamous 'phantom goal' in the Bundesliga, and here he scored twice, either side of a Simon Rolfes penalty and Sidney Sam's effort to give Sami Hyypia's men a fine victory.
