Switzerland coach Ottmar Hitzfeld showered Spain with praise ahead of their showdown on Wednesday but believes the European champions are beatable.
The two sides open their World Cup campaigns tomorrow in Durban with Spain expected to win.
However, Hitzfeld claims the Swiss can strike a blow for their country, and beat a team that they have always struggled against.
'Spain are one of the favourites to win the title but we have nothing to lose,' he said. 'This is great opportunity for us.
'We could be one of the teams that could make one of the favourites tumble. The probability is there. Every player of the Swiss team has an opportunity to showcase his talent. At one point we are going to beat Spain and why not tomorrow!'
Nevertheless, the veteran German is in awe of his team's first opponents.
'Spain has a team of the century,' said Hitzfeld. 'They have incredible talents, an enormous selection of skillful players.
'They are very compact, they can focus on attack, but they are virtually perfect at the defensive end. They just don't focus on scoring goals but also on being organised in every line.'
Hitzfeld will be forced to make changes to his team with news that captain Alexander Frei and Valon Behrami will play no part.
Frei has an ankle injury and is set to be replaced in attack by Eren Derdiyok, while West Ham midfielder Behrami has a thigh problem.
'As for who will play up front, I will decide on match day,' said Hitzfeld. 'I am not going to announce the line up today. However, as to who will captain the team, it will be Gokhan Inler.'
Hitzfeld is hopeful of having Frei available by the end of the week. 'Frei has made tremendous progress after sustaining an ankle injury,' he said. 'He is getting better. It's just a sprained ankle and the aim is to have Alex in training on Friday.'
