There was final-day drama in Mexico and Venezuela, while the Argentina Clausura seems set for a similarly tense finish over the coming weeks. Shocks were in store for leading teams in Thailand, USA, Singapore and Korea Republic, while Adriano's long-awaited return represented the highlight of round four in Brazil. Join for a journey to all corners of the globe.

Argentinian Clausura: Full-steam ahead for leaders
The top three sides, Lanus, Velez Sarsfield and Huracan, all claimed maximum points and with three weeks remaining, the Clausura seems likely to be decided on the last weekend. Lanus maintains a one-point grip on top spot thanks to a 2-1 home triumph over San Lorenzo. Velez had Jonathan Cristaldo to thank for their 1-0 win against Gimnasia Jujuy, for whom the defeat confirmed their relegation. Sitting a further point back in third are Huracan, who defeated Banfield 2-1.

Big game: River Plate's slim hopes of a Clausura triumph were finally snuffed out after an uninspiring goalless draw with struggling Argentinos Juniors at the Estadio Diego Armando Maradona. The result leaves the Buenos Aires giants ten points behind Lanus, while Argentinos Juniors share last place alongside Gimnasia Jujuy and Arsenal.
The predatory instincts of veteran striker Martin Palermo appear as sharp as ever, with the 35-year-old scoring twice to help Boca Juniors to a comfortable 3-0 victory over San Martin.

Campeonato Brasileirao: A star returns shining brightly
Internacional maintained their sensational start to the campaign, maintaining their 100 per cent record with a 2-1 win over Avai. Talles Cunha and Alecsandro grabbed the goals for the team that also have one foot in the Copa do Brasil final after their first-leg win over Coritiba last week. A last-gasp winner from Leandro Domingues proved vital for Vitoria with the 1-0 triumph over Gremio enough to see them secure second place, three points off the pace.

Big game: Champions Sao Paulo earned a much-needed first win with a 3-0 victory over Cruzeiro at the Morumbi courtesy of goals from Washington, Borges and Dagoberto.
Former Inter Milan striker Adriano overcame the weight of expectation to score on his return to his native Rio de Janeiro after eight years in Europe, helping his Flamengo side to a 2-1 win over Atletico Paranaense. Adriano nodded home less than a minute after the interval with what proved to be the winner, helping his side into sixth position in the 20-team competition.

Thai Premier League: Newcomers continue to surprise
Top flight newcomers Muang Thong United began the weekend by taking a surprise lead in Thailand with a come-from-behind 5-2 win over perennial challengers Chonburi United. Trailing by two goals after the half-hour, Muang Thong were unstoppable in the second half and duly jumped from fourth to first. Unbeaten leaders Bangkok Glass took back poll position 24 hours later despite only managing a 1-1 draw with Bangkok United.

Big game: Defending champions Provincial Electricity Authority were held to a surprise 2-2 home draw by Thai Port and remain entrenched in the bottom half of the ladder with just two wins from 12 outings.
A quickfire double from young Ivorian defender Dango Siako within the space of eight minutes changed the complexion of Muang Thong's vital encounter with Chonburi.

American Major League Soccer: Shock for leaders
FC Dallas secured one the upsets of the season by handing Eastern Conference leaders Chicago Fire a comprehensive 3-0 defeat. Goals from Jeff Cunningham and Kenny Cooper, plus a CJ Brown own goal, saw Dallas earn just their second win, although the Fire still hold a five-point lead at the top. LA Galaxy's run of draws continued with a 1-1 tie away to Kansas City, a result secured only by a late equaliser from Edson Buddle.

Big game: Seattle Sounders saw another sell-out crowd attend their home encounter with Columbus Crew but a 1-1 stalemate ensured Houston were able to leapfrog the Sounders into second on the Western standings.
Conor Casey scored a brace in Colorado Rapids' 3-2 win over New York Red Bulls to take an outright lead at the top of the golden boot table with eight goals.

Pumas UNAM won the Mexican Clausura in dramatic style, snatching a 3-2 aggregate win over hosts Pachuca with the second leg finishing 2-2 after extra time. Pumas substitute Pablo Barrera's scored the winner in the 107th minute, enabling Pumas to clinch their sixth domestic title overall and their first since 2004. Earlier, newly-capped Argentina international Cristian Gimenez had twice put the home side in front, while Paraguay forward Dante Lopez first for Pumas.

Caracas FC claimed a record tenth Venezuelan Championship, their sixth title this decade, with a comfortable second-leg win over Deportivo Italia in the national decider. Deportivo, seeking their first title since 1999, were well placed after the first leg having secured a 1-1 draw but Caracas, who have also reached the last eight of the Copa Libertadores, dominated the second leg to win 5-0.

Singapore Armed Forces spurned a golden opportunity to take the lead in the Singaporean S-League, losing 2-1 away to Home United in one of the traditional highlights of the domestic calendar. Peres de Oliveira's winner five minutes from time helped the home side climb to fifth, but still well behind leaders Gombak United, who maintain their one-point advantage over SAF.

The Korean K-League title race has been blown wide open, meanwhile, with FC Seoul beating leaders Gwangju Sangmu 2-1 to move to within goal difference of the top spot. Seoul, coached by former Turkey coach Senol Gunes, have played one match more than Gwangju, while hot on their heels are Jeonbuk Motors and Incheon United, who sit just two points adrift and have a game in hand over the leaders.
