Karl Robinson says Charlton have rejected a bid from Forest Green Rovers for Dillon Phillips.
The League Two club were believed to have tabled a £60,000 offer.
But Robinson confirmed Phillips, who is behind Ben Amos in the pecking order at the Valley, will be going nowhere until a replacement is signed.
The Addicks boss said: “We rejected a bid this week [from Forest Green Rovers]. I’ve been quite clear with the stance on that.
“Unless I can get a number two in as good as Dillon Phillips to replace him, the boy doesn't go anywhere.”
And the club did so yesterday to extend his Valley deal until the summer of 2019.
Reeco Hackett-Fairchild, Jamie Mascoll, Josh Umerah and Kenneth Yao also extended their contracts by an extra year.
