The Bluebirds have lost three of their last four matches in the top flight, leaving them 19th in the table.
The defender told the club's website: "We did well at Everton, despite losing the game. We knew that Everton were going to push us hard and that our defence had to be very attentive.
"What we have to do now is work hard to beat Liverpool. I think in this last fortnight we have seen another Cardiff City, working much harder, a better team.
"Playing at home will help us and I think if we can win our home games we will stay in the division. In front of our home fans I think everything is possible."
Cardiff host Liverpool on Saturday.
