Boss Billy Davies has himself questioned the wisdom behind the decision that has coincided with a miserable run of six straight away defeats which has seen the Reds lose considerable ground on leaders Newcastle and second-placed West Brom.
But Pleat told BBC East Midlands Today: "Every player that has been suggested by the manager has been enquired about and some just aren't available.
"Every club has an acquisitions panel, it is just a name. There is a anti-feeling towards it in the media because they think it is interference - but it is not. It may be that players who have been recommended haven't been wanted by the manager and he has the final say.
"The supporters must keep faith. The club is in a far better position than it was, it is progressing steadily and it has got good people guiding it."
