Paraguay midfielder Cristian Riveros insists his team cannot afford to calculate ahead of their second Group F clash, against Slovakia on Sunday. The South Americans held world champions Italy to a surprise draw in their opener and victory against Slovakia would leave them with one foot in the knockout stages.

Coach Gerardo Martino believes his team can progress with two draws but Riveros is refusing to look at the permutations. The Sunderland new boy said: "There is no time to speculate on games. We have to try to go in search of the game, as a victory for us would be putting us very nearly on the other side. We are with that mentality and let's hope things will happen for us to be able to pick up the three points."

All four teams in the group have a point following Slovakia's draw against New Zealand. And Riveros is expecting another tough battle on Sunday. "This team is different [than Italy]," he continued. "In this match we will have a lot of the ball. We will have to be precise in our passing, be patient, because they give you the initiative. They allow you to hope a bit, but at the slightest error they go on the counterattack.

"They also have the obligation to win because they also have a point, and so losing or drawing out there is of little use to the team, as much for them as for us. But I doubt much will change. We have to think about ourselves, in trying to do our work, having a lot of the ball, something we lacked against Italy, and much of the chances we have to win this game will depend on that."
