Leyton Orient manager Ian Hendon has insisted that top scorer Jay Simpson will not be sold cheaply if another club tries to sign him in January.
Simpson, 27, has netted 16 goals this season, prompting speculation that he could attract interest when the transfer window reopens.
"It would be a considerable amount of money if anyone wants to make an offer," Hendon told BBC Radio London.
"As far as I'm concerned, and have heard, no-one has come in for him yet."
Orient are ninth in the League Two table and have won just one of their last seven matches in all competitions.
Hendon has therefore told club owner Francesco Becchetti he believes new players must be brought in.
"I've spoken with the owner and he's aware that I want to sign some players," he said.
