Cardiff manager Neil Warnock
The Bluebirds are currently languishing second from bottom in the league table after only two victories from their 11 games this season. But one of those wins came in their last match against Bristol City, which incidentally was new boss Neil Warnock's first game in charge.
And Jones is wary that Warnock, who used to manage Sheffield United, will have brought positive changes and a new belief into the Cardiff City dressing room.

The former Burnley man also insists that Warnock's experience at Championship level is vital, and will no doubt make facing Cardiff a tougher prospect, especially at home.
Jones told The Star: “We know whatever team he [Warnock] puts out will be very organised and know what their jobs are to do.
“He’s a very good manager of massive experience in this league.
“It will be a very difficult game and we need to be on top of our game to get anything from it. If we are not, we won’t win the game. It is as simple as that.”
Wednesday fly to South Wales to face the Bluebirds looking for their sixth win in their last eight games.
Their latest victory came at the hands of high-flyers Huddersfield Town, who had won all five of their home games before Wednesday snatched a 1-0 win at the John Smith's Stadium.
