Darren Patterson said that although he would have liked to sign striker Matt Green, he still has plenty of other irons in the fire.
Green snubbed Oxford for Torquay at the weekend.
"Fortunately we have other targets, and have continued to talk to other strikers who are as good or better," he said.
"There are some very exciting players who would love the chance to play here, but we will be patient and make sure they are the right players for this club.
"We will continue to build a squad that is totally united for the coming season.
