Brazil striker Hulk insists revenge is not on the agenda as the World Cup hosts bid to all but secure their place in the last 16 against rivals Mexico on Tuesday. Mexico shattered Brazil's dream of winning the only major prize missing from their honours list two years ago, when they stunned the South Americans 2-1 to claim the Olympic gold medal in London.

But Hulk insists there is no question of Brazil looking to settle a score as they face the Mexicans at Fortaleza's Castelao Stadium. It is the same venue where they met in the group stage of the Confederations Cup last year when Luiz Felipe Scolari's side claimed a 2-0 victory. That success means a measure of revenge has already been exacted, and forward Hulk insisted that Brazil will only have one thing on their minds come kick-off on Tuesday. "In the Confederations Cup we tried to think only about winning the game and it will be the same this time. If we think about revenge it could cause us problems," said the powerful forward, who scored in the Olympic final clash. Nevertheless, the Olympic defeat left its mark on him, Thiago Silva, Marcelo, Oscar and Neymar, the five members of Brazil's 2014 squad who featured at Wembley. "Of course I was very sad. It is a medal that Brazil have never won and we lost the final," said Oscar.

The current Mexico side, featuring eight members of the gold medal-winning 2012 team, also started their Group A campaign in positive fashion, beating Cameroon 1-0 in Natal on Friday. Oribe Peralta scored the only goal in that game, although Brazil are quite familiar with his threat - he netted a brace in the Olympic final as well.

‘Dark Horse’ enters into the fray:

Belgium's vibrant young team are preparing to launch their World Cup campaign against Algeria on Tuesday with competition hotting up on the training pitch ahead of the Group H clash. Seen as dark horses to lift the trophy, the richly talented squad is blessed with players such as Chelsea playmaker Eden Hazard, powerful striker Romelu Lukaku and Manchester City defender Vincent Kompany. Belgium have not appeared at a major international championships since the 2002 World Cup in Japan and South Korea but they impressed in qualifying and will fancy their chances of matching their semi-final showing in Mexico in 1986.

Coach Marc Wilmots can also call on young Manchester United sensation Adnan Januzaj and his club team-mate Marouane Fellaini as well as Chelsea goalkeeper Thibaut Courtois, outstanding while on loan at Atletico Madrid last season. Despite their impressive playing resources, Belgium will come up against a side looking to cause an upset of their own to go alongside their shock win over eventual finalists West Germany in 1982. Despite that famous win, Algeria, taking part in their fourth World Cup, have never gone beyond the group stages.

Returning Russia face Korean test: Out-of-sorts South Korea face a Russia side desperate to prove a point in Cuiaba on Tuesday. The Korean's fortunes have nose dived since the heady days of 2002 when they turned the formbook on its head by becoming the first Asian side to make it through to the semi-finals. But before reaching their eighth consecutive World Cup, they struggled in qualifying, squeaking home only on goal difference. They also lost World Cup warm-ups to Tunisia, 1-0, and more worryingly a 4-0 drubbing by Ghana last week. Coach Hong Myung-Bo is fretting over his Taeguk Warriors' fate in Brazil, aware that defensive frailties will make the going tough for them.

"The fact is that the quality of football in South Korea has developed a lot since 2002," he declared. "It's true the Russian team are quite technical and strong. Maybe the Russians are physically stronger than Asian sides like us but we are well prepared for this game, we're focused." Russia make their return to the feast of football for the first time since 2002, when like in 1994 they failed to make it out of the group stages.

Under Fabio Capello Russia coasted through qualifying and in stark contrast to Tuesday's opposition are unbeaten in 10 games. Veteran defender Vasily Berezutskiy says the 2018 World Cup hosts are in Brazil to set the record straight.
