Cardiff's hopes of avoiding the drop took a blow on Saturday as they were beaten 3-0 at home by relegation rivals Crystal Palace.
When asked if he felt that the Cardiff players were up to the task of securing enough points to avoid relegation, the Bluebirds boss told reporters: "Most of them. The ones that are going to be involved.
"I am saying the ones I pick will have belief in them - don't worry about that."
Cardiff sit 19th in the table following the defeat, six points adrift of safety.
