This weekend could see champions crowned in two of the most passionate footballing hotbeds on the planet, Brazil and Argentina. Meanwhile in Mexico, the Apertura title play-offs have reached the semi-final stage and on Sunday either FC Seoul or Suwon Bluewings will be celebrating championship glory in the Korea Republic. Once again, is here to preview the best of the action.

Brasileirao: Sao Paulo chasing three-in-a-row
After one of the most exciting Brazilian title races in years, just two sides are still in the hunt going into the final matchday: Sao Paulo (72 points) and Gremio (69). A point from their encounter with Goias at the Estadio Bezerrao in Gama would be enough for O Tricolor Paulista to clinch their third successive national championship and a sixth overall. Gremio, the season's surprise packages, welcome Atletico Mineiro to Porto Alegre needing a win and a huge favour from Goias to clinch a shock success.

Big games: Away from the title chase, Palmeiras, Cruzeiro and Flamengo are all competing for just two Copa Libertadores berths. Down at the bottom of the table, Carioca giants Vasco da Gama are on the verge of following already relegated Portuguesa and Ipatinga in to Serie B. Only two of Vasco, Figueirense, Atletico Paranaense and Nautico will survive.
Player to watch: If goalkeeper Rogerio Ceni, Sao Paulo's captain and fans' favourite, can keep a clean sheet against Goias, his side cannot fail to win another league title.

Argentinian Apertura: Another title for Boca Juniors?
Los Xeneizes have now gone four league campaigns without lifting the trophy, though an away victory over Gimnasia y Esgrima La Plata could seal the 24th league title of their glorious history with a game to spare. To do so, Boca, who hold a two-point lead over closest pursuers Tigre and San Lorenzo, need their two rivals to fall at the penultimate hurdle.

Big games: Sure to be closely following events in La Plata, San Lorenzo and Tigre will be desperate to take all three points from their respective encounters to keep the pressure on Boca. El Ciclón are at home to rivals Independiente while El Matador travel to face Rosario Central.
Player to watch: Twenty-year-old Sebastian Blanco is the danger man for a Lanus side on a five-match unbeaten run and which, mathematically at least, can still take the Apertura crown. Will Lanus have closed their four-point gap from Boca after their trip to Velez Sarsfield?

Mexican Apertura: Grand final in sight
The heat is really on in the play-offs for the Mexican title, which are now at the semi-final stage. On Saturday Cruz Azul travel to face Atlante looking to protect their 3-1 first-leg lead, while Toluca welcome Santos Laguna to the Estadio Nemesio Diez on Sunday after the pair ground out a 0-0 first-leg draw.

Big game:
The tie between on-form Toluca and reigning champions Santos Laguna, rejuvenated since the arrival of veteran forward Cuauhtemoc Blanco, is on a knife-edge ahead of Sunday's return match. Who will reach the final?
Player to watch: Santos Laguna's Argentinian attacking midfielder Daniel Luduena was a key figure in the club's Clausura 2008 success and seems determined to repeat the feat this time around. His ability to conjure up vital goals and assists could tip the balance for the Torreon outfit.

Hogging the limelight in Africa this weekend is the 11th round of matches in the South African top flight, where ABSA Premiership leaders Golden Arrows take on third-placed SuperSport United, who are just one point behind. Ajax Cape Town, second on goal difference, face a tricky visit to Orlando Pirates. Fans in the host nation of the next FIFA Confederations Cup and FIFA World Cup™ are in for a thrilling weekend of action.

And there's more. South Korea is sure to come to a standstill this Sunday as Suwon Bluewings welcome FC Seoul for the second leg of the K-League grand final. The evenly matched pair, whose rivalry has grown to impressive proportions over recent years, finished the regular season level on 54 points and drew Wednesday's first leg 1-1, though Suwon will have a slight edge by virtue of their away goal. will bring you all the key results and highlights of the weekend's global happenings in Monday's World Leagues review.
