Bosnia-Herzegovina coach Miroslav Blazevic has been playing up his team's prospects of causing a upset in Wednesday's FIFA World Cup™ play-off second leg against Portugal.

Portugal, semi-finalists at the 2006 FIFA World Cup in Germany, are in pole to secure the ticket to South Africa after taking Saturday's first leg 1-0. However, Blazevic believes that despite that defeat in Lisbon, his team can reach their first world finals.

"It is not impossible and it would not be the first time that a more decisive, weaker team defeats a better one," Blazevic told journalists on the eve of the match to be played in the central town of Zenica. "But it would be a lie to say that they (Portugal) do not have a team of good quality."

The 74-year-old, who led Croatia to third place at the 1998 FIFA World Cup, described the mood in the Bosnia camp as particularly "tense". "Normally in my long career I have had to inject tension; this is the first time I have had to calm things down."

During Saturday's match in Lisbon, the star-studded Portuguese side were saved by the woodwork on three occasions, including twice in the last minute.
