Six days into the FIFA Futsal World Cup and the race to secure a second-round place is slowly but surely hotting up. Sunday's intriguing encounters in Groups C and D could go a long way towards deciding matters in both sections. In the two Group C matches taking place in Brasilia, Argentina take on Ukraine, while China PR meet Egypt. An all-European duel in Group D, sees world champions Spain square up to Czech Republic in Rio de Janeiro, while in the same section Egypt's game against China PR is a clash of the reigning African and Asian champions.

The big game
Argentina-Ukraine, Sunday 5 October, 12.30 local time, Brasilia
Whoever emerges victorious from Sunday's clash between Argentina and Ukraine in the Nilson Nelson Arena will have every chance of going on to claim top spot in Group C. Both teams are currently unbeaten in the tournament, though the Albiceleste have contested one game more than the eastern Europeans. Ukraine's impressive 6-2 victory over Guatemala in their opening game augurs well for a lively and tightly-contested encounter which form on the day could decide.

The other games
After a stuttering start to the tournament, Spain's 3-0 win over Libya will have helped to ease nerves. The Iberians, though, cannot help but be concerned about their profligacy in front of goal against the north Africans, and coach Javi Rodriguez will be hoping for an improved performance from his charges when they take on Czech Republic in Rio de Janeiro. The Czechs, who kicked off with a 4-1 victory over Uruguay, will be looking to displace Spain at the top of the table with a win on Sunday.

Libya's game against Iran in the same group sees a clash between the reigning African and Asian champions. While Iran announced their intentions with an impressive opening draw against Spain, Libya have picked up only one point after two games. In their defence, however, the latter's first two opponents, Spain and Uruguay, rank amongst the tournament's top teams. Coach Mato Stankovic knows that only a victory will be good enough for Libya if they want to retain any hope of qualifying for the second round.

Another Asia-Africa duel, this time in Group C, pits China PR against Egypt, with both teams desperate to open their accounts with a first win at the tournament. The north Africans have had little joy so far in Brazil after their last-minute loss to Guatemala was followed by a narrow 4-2 defeat at the hands of Argentina. China PR, who likewise went down to the South Americans (5-0) will be looking not only to pick up their first points but also to score their first goal of the tournament at Sunday's encounter in Brasilia.

The Player
Tomas Meller, Czech Republic
The Czech keeper was in outstanding form in the game against Uruguay, allowing a solitary goal to pass between his posts. Against the reigning world champions, the Czech team will be relying heavily on the Era Pack Chrudim player to thwart Spain's offensive threat.

The stat
18- The number of times Spain have played against European opposition at FIFA Futsal World Cups. A tally of 16 victories, one draw and a single loss, to Italy in 2004, represents an impressive return for the Iberians.

What they said
"Without doubt, Argentina are the strongest team in our group," Gennadiy Lisenchuk, Ukraine coach
