"I know that there is interest because people are coming to watch him or they are coming to watch us and he is obviously impressing them," admitted manager Craig Brown.
"I am hoping that Ricardo can fulfil his ambitions with Preston North End.
"We are prepared to wait until the last minute and then if a daft offer came along then it would be accepted but that would be the worst case scenario.
"There is usually a bit of movement around the end of January because there is more pressure on managers either to sign or to sell.
"It is hypothetical because I haven't had any offers and I haven't had any interest.
"Hopefully he will continue to play well and hopefully we will keep our player but you can never predict what will happen."
