A confident Croatia is ready to spoil Brazil's party in their World Cup opener and continue a tradition of first match upsets at the tournament.

With all the pressure on the host team, Croatia coach Niko Kovac said Wednesday that his team can deliver a "historic result" in Thursday's match in Sao Paulo.

Kovac acknowledged that Brazil is the clear favorite in the Group A game, but added that few teams would like to face his squad either.

He said "We are a tricky side and we will show that tomorrow."

Even a draw would significantly enhance Croatia's chances of advancing from a group that also includes Mexico and Cameroon.

In previous upsets, Senegal beat holder France in 2002 and fellow holder Argentina lost to Cameroon in 1990.
