The Cottagers have lost their last three league games without scoring, but Kacaniklic is confident that they can beat Reading, Liverpool and Swansea City to end the season on a high.
"We need a win on Saturday," Kacaniklic told the club's official website. "It's a home game in front of our own fans so it would be nice to get back to winning ways at the Cottage. We haven't won for a while now so at the weekend we won't be looking for anything other than three points.
"There are three games left and we want to win every one of them. That should always be the mentality – to go into every match and want to win. That's what we need to do, first of all on Saturday, and then again when we face Liverpool and Swansea."
The game against relegated Reading kicks off on Saturday at 3pm.
