"For how long can they sustain the actual model that they have and still be a top-four club? You can look at them and say Stellenbosch has probably put themselves among the top clubs with a model that will come back to bite them," he told iDiski Times.
"How they go about it is another thing and that obviously is down to squad depth, down to the recruitment, how well they have done that because look you don’t get a goal scorer like Rayners every other day. He is someone that has been built over time because you must remember he has also been away from Stellenbosch after he left them initially.
"So he has been through experiences that have seen him grow into the player that he is now. So to bring in someone to kind of just to fill in and seamlessly take over his job, I don’t think that will happen so, they have some tough questions to answer," Paulse continued.
"But I’m sure even on the business side as well, I am sure if they agreed to the transfer then they had a contingency plan in place."
