Portugal captain Cristiano Ronaldo is confident that his side will show their "superiority" over Bosnia in their Euro 2012 play-off clash on Tuesday after struggling with a difficult pitch in the first leg.
The two sides drew 0-0 in Zenica last Friday, with many pointing to the poor quality of the boggy playing surface as a key reason for Portugal's failure to grab an away goal.
But Real Madrid superstar Ronaldo believes that playing on a better pitch in Lisbon will allow Paulo Bento's side to cast off the shackles and produce an attacking display that will help them advance to next summer's tournament in Poland and Ukraine.
"That wasn't grass, we played on a vegetable patch. It was very difficult and still we did well and created chances," Ronaldo said.
"We now have a second chance at home in front of our fans, with a good pitch and have all the conditions to ensure we win. We have to assume we are favourites and show our superiority - we are a better team."
But Bosnia's Edin Dzeko believes his side will benefit from a slicker pitch just as much as their Portuguese hosts, and the Manchester City striker insists they are full of belief that they can qualify.
"Maybe the Portuguese think we will be easier opponents on a better surface but we won't," Dzeko said. "The fact is that we are also looking forward to play on a quality pitch."
