The 30-year-old, who was banned for two years by UEFA in 2010 for failing to inform the authorities of being approached by fixers ahead of European games against Liverpool and Fiorentina, has been accused of being paid to fix the game at Anfield in 2009.
"Anyone who watched the match would know that what people are saying is bull," Poleksic told the Daily Mail. "We lost 1-0 at Liverpool and I played a good game.
"I made lots of saves - a one-on-one against Albert Riera, one from Fernando Torres, one from Steven Gerrard. I remember it all. How can anyone say I threw the game?"
Europol announced earlier this week that 380 matches are under investigation for match-fixing.
