I think it's a different situation - RdP is covering for our clear first choice who is out injured. Rohan came in when we had no clear first choice centre, and from day one he was a permanent contract target, but he didn't want to cut out on his SR contract (if rumours are to believed he agreed to a long term deal when he signed for us on loan, but it couldn't be announced until his SR commitments were done).
Of course there is always the possibility that we will heavily target RdP, especially if he performs really well, but we recently signed AJ to a very long term contract and we have Kieran Wilkinson pushing from the academy and really impressing, so 10 isn't a major concern right now.
