Naysmith, who made nearly 90 appearances for United before retiring last year, explained: "We have now built up a relationship with Sheffield United and if, in the future, we feel that they have a player who will benefit from a similar situation as Callum, we will try to do that."
Semple, aged 20, is now expected to be placed with a team in the English Football League has he continues his development.
Naysmith, admitting he has encouraged managers south ofthe border to sign the centre-half, added: "It is a market that I am looking to get into more with some of my ex-clubs, to try and get a link-up and make us a bit of a feeder club for some clubs in England.
"Players are better coming up here and playing in the Championship rather than playing under-23 football with their clubs."
