"I feel most of the players just gave up and accepted the situation, some of them knew they would be going at the end of the season," he said.
"It is disappointing when people have that attitude. We have responsibilities, we are not just here to take the money and it's hard to respect those players who were not trying."
He added: "There have been a lot of question marks over some of the players at the club. This season, I have seen a change in the attitude of some of the players during training.
"The players did not enjoy it as much, and some of them were just coming in to pass the time. You would try hard to get the spirit back during the week, only to find that during the game it would go again.
"But Dominic, Smithy and a few others always worked hard for the club and it is sad to see them end up in this situation."
Radebe concluded: "What you need to come back up is to have quality and fighting spirit in the team and, while I realise that some players will go, the people who stay at the club must fight to come straight back up."
