PRETORIA (Reuters) - Hosts South Africa trumpeted their World Cup credentials with a morale-boosting 1-0 win over Denmark on Saturday, completing a remarkable turnaround in form over the last nine months and setting out their potential for next Friday's opening match of the tournament.

Striker Katlego Mphela grabbed a fifth goal in as many games at the end of an intricate 76th minute passing move that encapsulated the philosophy the side have absorbed from coach Carlos Alberto Parreira.

Written off last year as they tumbled down the world rankings, South Africa have now gone 12 games without defeat since the World Cup-winning Brazilian coach returned to the helm of the team in November.

Parreira played his likely first choice line-up at Atteridgeville's Super Stadium, in a final run-out before meeting Mexico in the World Cup opener on June 11.

South Africa finished the stronger, though, thanks to intense fitness work over the last three months at training camps in Brazil and Germany, with Danish goalkeeper Stephan Andersson making two saves in quick succession to deny Siphiwe Tshabalala and Mphela just after the 70th minute mark.

The goal came after a swift passing move through midfield and out wide to Mphela, who cracked home a shot from an angle on the right.

Denmark have lost two warm-up matches in South Africa this week, also beaten on Tuesday by Australia in Johannesburg.
