Bayern's new boys make mark

Bayern Munich's four summer signings - Luca Toni, Miroslav Klose, Hamit Altintop and Ze Roberto - all scored to put their side top of the Bundesliga with a 4-1 win at Karlsruhe on Sunday.

Toni scored his fourth goal of the season with a deft chip over Karlsruhe 'keeper Markus Miller in the fifth minute, while Miroslav Klose followed up Miller's save from an Altintop shot to poach his fifth goal this term.

Altintop claimed his third goal in a Bayern shirt just four minutes into the second half, so between them Toni, Klose and Altintop have now scored 12 of their side's 16 goals this season.

Midfielder Ze Roberto, back after a season in Brazil, wrapped up the scoring with a well-timed strike on 75 minutes as Bayern picked up their fourth win. Along with Schalke 04, Bayern are the only unbeaten team in the Bundesliga.

But coach Ottmar Hitzfeld singled out Toni for special praise. "Luca Toni is a phenomenon in front of goal," said Hitzfeld. "His goal was very well taken and he has an incredible instinct. The scoreline makes it appear an easy win, but it was a tough game and Karlsruhe didn't make things easy for us."

Bayern Munich captain Oliver Kahn, playing his last league game before retirement at the place he started his career, was only tested when Massimilian Porcello beat him to score a second-half consolation goal.

And Kahn, 38, admitted his final league appearance at Karlsruhe pulled at the heart-strings having been born and raised in the south German city.

"I felt a bit emotional before the game," he said. "It was the place where I started my career and I have lots of happy memories. I have had many experiences in football, but you never forget the place you come from."

The result puts Bayern top of the table by two points from second-placed Hertha Berlin and they can expect another three points from Wednesday night's trip to Energie Cottbus as the Bundesliga has a rare round of midweek games.

Bayer Leverkusen went third in the league after their 3-0 win over Hanover when German striker Stefan Kiessling scored his first goal of the season, Chilean defender Arturo Vidal and Greek striker Theofanis Gekas adding goals.

Hertha had taken a temporary lead on Saturday as they picked up their fourth win of the season after coming from behind to beat Borussia Dortmund 3-2 at Berlin's Olympic Stadium.

The Berlin-based side are now second with Arminia Bielefeld dropping to seventh as Schalke 04 hit them with a convincing 3-0 defeat to keep their unbeaten record and move to fifth.

Striker Hugo Almeida hit two goals in 54 seconds on Saturday as Werder Bremen beat Bundesliga champions VfB Stuttgart 4-1. The win leaves Bremen eighth in the league, while defending champions Stuttgart are now 13th, just five places from bottom.

Hansa Rostock picked up their first win of the season to move off the bottom of the table with a 2-0 win over Duisburg. Striker Sebastian Haehnge opened the scoring on 34 minutes before striker Enrico Kern converted a 53rd minute penalty.

Hamburg got their third win of the season as captain Rafael van de Vaart hit a second-half goal to seal a 1-0 win against Nuremberg.

Energie Cottbus took over as the Bundesliga's bottom side when they were humbled 2-1 at home to VfL Wolfsburg and promptly sacked their coach Petrik Sander on Sunday.

On Friday VfL Bochum and Eintracht Frankfurt ground out a 0-0 draw.
