The experienced attacker is eagerly anticipating Friday's World Cup qualifier and believes the supporters could play a key roleIvica Olic is confident that Croatia can get a good result against Serbia with the support from their fans, and has stressed that his side will press their opponents right from the start.
The Wolfsburg attacker expects a partisan atmosphere when both sides lock horns in Zagreb on Friday, and he thinks the Croatia fans' passionate support could cause their youthful rivals problems.
"The atmosphere at the stadium will be a big advantage for us," Olic was quoted as saying by Jutarnji List.
"Serbia have a pretty young team and it will not be easy for them to withstand the Croatia fans at the Maksimir Stadium.
"We must start pressuring them right from the start. That's what the fans will expect from us and we cannot let them down.
"Why would we sit back and hope to score a goal late in the game? We will go for it right from the first whistle."
Croatia currently sit joint-first in Group A with 10 points from four games, while Serbia have collected four points from as many matches.
