Group C leaders Brazil are the only side in action on day seven of the FIFA Futsal World Cup Thailand 2012 to have already made sure of their place in the Round of 16. In their final group game the Brazilians take on Portugal, who are fighting it out for second with Japan, although one of the two could well go through as one of the best third-placed sides.

The situation is even tighter in Group A, where Ukraine lead the way by a solitary point from Costa Rica and the host nation, while bottom-placed Paraguay still have a chance of elbowing their way into the last 16.

Match of the day 
Paraguay-Thailand (Bangkok, Indoor Stadium Huamark, 21:00)

With so much at stake, this promises to be a truly tense affair. Tipped to progress by the pundits before the group got under way, the Paraguayans, who have just one point to their name, have no option but to win. The return of star striker Enmanuel Ayala from suspension will surely help them in their bid to do just that.

The Thais have more margin for error but will not want to rely on the results of other games. Though outclassed by the Ukrainians in the first half on Sunday, the hosts gave a very good account of themselves after the restart, raising hopes that they could yet progress. Those hopes hinge to some extent on whether their star man, Suphawut Thueanklang, can recover from the injury he sustained against the eastern Europeans.

Other highlights 
In the other game in Group A, Ukraine take on a Costa Rica side buoyed by their big win over Paraguay at the weekend, which has given them a chance of topping the section and thereby avoiding one of the big guns in the first knockout round.

Brazil, the side everyone will want to avoid in the last 16, play their final game in Group C against Portugal, who lie second in the section on four points and look well placed to progress.

Third-placed Japan secured their solitary point thanks to a dramatic comeback against the Portuguese and now need to beat Libya to stay in the hunt. If they are to have any chance of advancing, the north Africans have to win and hope results elsewhere go their way.

Player to watch 
Cardinal (POR) 
Scorer of just two goals at Brazil 2008, the 27-year-old pivot has already bagged five in Thailand. A skilful and opportunistic finisher who has impressed everyone with his eye for goal, the No7 is proving a real handful for opposing defenders.

The stat 
19 - The number of matches reigning world champions Brazil have gone without defeat, the second-best run in the history of the competition, just four games short of the all-time record they themselves set between 1988 and 2000.

The words 
“The match with Libya is a final for us. We are determined to make history and reach the next round for the first time ever,” Japan coach Miguel Rodrigo.
