's review of club action outside Europe this week takes us to Brazil, USA, Japan, Australia, Argentina and South Africa. While it is still early days in Argentina, elsewhere it proved a bad weekend for the leading clubs, with the front-runners in all featured nations save for South Africa failing to claim maximum points.

Brasileirao: Fascinating struggle among leading pack
The fixture list threw up an enthralling combination as the top four sides met, with Internacional the big winners thanks to their sensational 4-0 home win over Goias in Porto Alegre. The match started badly for Goias with the early dismissal of striker Fernandao, while Marquinhos, Pablo Guinazu, and Giuliano and Kleber all hit the target to pile on the agony. Leaders Palmeiras battled to a goalless stalemate with crosstown rivals Sao Paulo, but remain top with a three-point lead over Goias.

Big game: Flamengo edged further away from the drop-zone with an important 3-0 win at the Maracana. Denis Marques, Leo Moura and Ze Roberto all scored to move O Mengao into 11th, six points clear of danger.

American Major League Soccer: Top guns pinned back
Bottom-placed New York Red Bulls secured arguably the upset of the season by defeating high-flying Columbus Crew with a lone 83rd-minute goal from Jamaica international Dane Richards. It was the second consecutive loss for the Crew, having crashed to Mexico's Cruz Azul 5-0 midweek in the CONCACAF Champions League, though they still hold a one-point lead in the Eastern Conference with a match in hand. Chicago Fire spurned the opportunity to take pole position, going down to the visiting DC United thanks to Bryan Namoff's first-half header.

J-League: Leaders struggle for form
Kawasaki Frontale missed a golden opportunity to make a serious dent into the lead of defending champions Kashima Antlers, who were surprisingly beaten by Omiya Ardija 3-1 a day earlier. Frontale managed to reduce the deficit to seven points but were fortunate to do so, relying on an injury-time equaliser from defender Hiroki Ito to force a draw with Shimizu S-Pulse.

Australian A-League: Long wait over
A solid 2-0 win over Wellington Phoenix allowed Sydney FC to move to the top of the standings for the first time in four years. Youngster Brendan Gan and veteran striker John Aloisi scored second-half goals to allow the Sydneysiders to edge past Gold Coast United, who suffered a surprise loss to Newcastle Jets, with the only goal of the game coming from striker Sean Rooney.

Elsewhere, evergreen striker Martin Palermo scored the winner for Boca Juniors, who battled to a hard-fought 2-1 away victory over last season's surprise packages Lanus.

In South Africa, Orlando Pirates continued their bright start to the campaign with an impressive 4-0 defeat of Jomo Cosmos. Thulasizwe Mbuyane proved the star of the show with a hat-trick to help his side establish a three-point gap at the top after four matches.
