Clayton Donaldson's agent says the Crewe Alexandra striker is not looking to play in League Two next season.
Donaldson is out of contract at Gresty Road and last season's top scorer has been offered a new deal to stay at Crewe.
He is also wanted by Bradford City, and has been linked with Football League new boys Crawley Town as he weighs up his future.
However, his representative Andy Sprott says the forward is keen to play at a higher level amid rumours Chesterfield are favourites to secure his signature.
"Clayton is not looking to play in League Two," Sprott told The Sentinel.
Bradford boss Peter Jackson, meanwhile, is not giving up on signing Donaldson, but accepts the player is unlikely to arrive at Valley Parade.
Jackson said: "It is no secret that we are interested in bringing Clayton to the football club. There is, however, no doubt that several other clubs would like Clayton's services as well.
"I know for a fact that some so-called bigger teams further up the league structure have spoken with him as well as ourselves.
"We are not admitting defeat yet - Clayton knows how much we want him here - but there is certainly a lot of competition for his signature.
"Once someone from a higher division comes in for one of your targets, then you've always got a battle on your hands to sign him."
