Port Vale manager Lee Sinnott has made five players available for loan or permanent transfer.
Valiants boss Sinnott revealed Shane Tudor, Mark McGregor, Charlie O'Loughlin, Paul Edwards and Jason Talbot were listed in a circular sent out to clubs.
He told the club's official website: "What we have said is they are available on loan or for a permanent transfer and we will see what comes back.
"As I have said before, I am dictated by budget and I have brought six players in, and hopefully that will shortly be seven, and the budget will only stretch so far.
"When you bring players in, obviously players' opportunities are restricted, so it works both ways. I have had a chat with Mark and Jason. Their contracts are up at the end of the season and I am just giving them an early indication of what we are thinking."
He added: "I have had no interest for any of my players since January 1, but this circular will go out and hopefully somebody will be getting in touch with us. If we are looking to bring anybody else in we have now come to the stage where people have to go out."
