Crewe boss Gudjon Thordarson is keen for John Brayford's future to be resolved amid interest in the defender from Derby.
Rams manager Nigel Clough, who knows Brayford from their time together with Burton Albion, has confirmed the right-back is among his transfer targets.
Thordarson does not want to see the impressive 21-year-old depart for Pride Park, particularly if any move occurs towards the end of the transfer window.
The Railwaymen kick off their League Two campaign with a home meeting against Dagenham & Redbridge on 8th August, when Thordarson wants Brayford to still be part of his squad.
"I don't know what is happening with John. There is definitely interest there from Cloughie because he has spoken about him on quite a number of occasions this summer," he told the club's official website.
"There is no offer for him and I don't want to sell him because John is going to be a key player for me. Of course, Crewe has always survived by selling their better players and that is the way it has to be.
"Every player in the world has a price but we won't be selling him for anything less than what we think he is worth.
"The club paid significant money to take him here in the first place and he has a long contract with us, so we'll have to see if Derby or anyone else comes up with the money we require.
"It could become a concern for me because I am trying to plan my team for the new season with John as an important part of it.
"I don't want it to drag on until the eve of the season and then in a flash of smoke he has gone because he would be another influential player I would have to replace."
