The Clarets are the only side in England's top four divisions to have not won a match this season, and they have also not recorded a victory against the Gunners in North London since 1974.
However, despite the odds being stacked against Sean Dyche's men, Ward has refused to rule out the possibility of a shock result.
"The games against the top five or six are very tough and going to Arsenal next week nobody will give us a chance," he told the Lancashire Evening Telegraph.
"There's always pressure to perform. We want to go out, give it a go, and hopefully cause an upset. You just never know in this league."
When the two sides last met at the Emirates Stadium in March 2010, hosting Arsenal ran out 3-1 winners.
