Manchester City winger Vladimir Weiss has warned Slovakia's players to be wary of Paraguay striker Roque Santa Cruz.

Weiss knows City striker Santa Cruz well and says the Paraguay international is desperate to make a big splash at the World Cup.

"Roque has been bothered by injuries ... he is natural goalscorer.

"He is big man, very strong and difficult to shake off the ball," he said. "We know what he is capable of but it is not all about him as Paraguay have a lot of good players."
