Dundee United are still looking to bring in Darren Dods, David Proctor and Ian Black, but manager Craig Brewster is aware he needs to sell before he can buy.
Inverness have so far stood firm over the futures of their trio, but are bracing themselves for a renewed attempt from Brewster.
The Terrors chief is keen to have new faces in place before the start of the season, but is aware that he needs to trim his own squad before bringing in fresh blood.
"I discussed a number of things with the chairman, including signing targets," he told the Daily Record. "But we need to get boys out first.
"The fans have backed the club by buying season tickets so I can understand if they're upset at the lack of activity.
"Things have not gone great but we can't change things overnight. I've said it before but this is a long-term job."
Former Dundee United winger Andy McClaren is poised to sign for Tayside rivals Dundee, following his release from Morton.
