Arsenal leads Group G, two points ahead of Dynamo Kiev, which won at FC Porto 1-0 and replaced the Portuguese team in second place. After two defeats in a row and its first home loss in the competition since 2005, Porto is four points behind Arsenal and Fenerbahce six behind.

Goals by Miroslav Klose and Bastian Schweinsteiger in the first 25 minutes put Bayern on the way to a victory over Fiorentina, and the Germany champions, currently 11th in the 18-club Bundesliga standings, are two points clear of Lyon, which won at Steaua Bucharest 5-3.

"It was an important game for us because it is the start of the next few weeks of playing two games a week," Bayern coach Juergen Klinsmann said. "I was really satisfied that we kept up the tempo for a full 90 minutes. And we need that in the coming weeks."

French champion Lyon was two goals down in the first 11 minutes but Karim Benzema and Fred scored two goals each in the comeback.

Juventus ended Real Madrid's perfect start with a victory in Turin helped by Alessandro Del Piero's 25-meter (yard) strike after only five minutes. Brazilian forward Amauri added a second in the 49th and Ruud van Nistelrooy replied for Madrid in the 66th.

"Tonight we were a little bit lucky, but we played well and didn't give them the space to play like they are used to," Juventus coach Claudio Ranieri said. "Real is used to starting a game at 1,000 kilometers per hour and we wanted to do that to them tonight and that is what we did by starting with an incredible first 20 minutes."

The players and fans held a minute's silence before kickoff as a mark of respect to the two Juve fans who died in a bus accident on the way to the game.

The Italian club went to the top of Group H with seven points, while Madrid has six. Both are well clear of BATE Borisov (two points) and Zenit St. Petersburg (one), who drew 1-1.
