Iran will face an Improved Mexico This Sunday at the 2006 FIFA World Cup

Mexico wants to prove they are an improving force against Iran this Sunday.

Despite the departure of goalkeeper Oswaldo Sanchez following the death of his father, the surprise semi-finalists from last year's Confederations Cup are determined to put past FIFA World Cup failures behind them.

"We have the belief we can achieve anything after the success of the Confederations," Mexico midfielder Pavel Pardo said.

"If we play like we did then, taking every game like a cup final, then we can go even further. Maybe the FIFA World Cup final.

"We don't care about the past or what people think, we are here to change that and win," added Pardo.

Mexico, who have qualified 12 times, failed to go beyond the second round in the last three FIFA World Cup tournaments.

Captain Rafael Marquez, generally a holding midfielder, is expected to move in to central defence to direct a back five who have been shaky in recent months.

Keeper Sanchez is due to return to Germany on Saturday and will be keen to play in his first FIFA World Cup after being a non-playing substitute at the 1998 and 2002 tournaments.

Jared Borgetti, Mexico's most prolific scorer, will have his work cut out against Iran's defence.

"This is the best team in the history of the Islamic republic," said Iran striker Ali Daei. On Sunday, against Iran, the rest of the world will find out just how good Mexico has become.
