Hull City boss Phil Brown insists he can do no more to bring new signings to the KC Stadium before the start of the season.
Brown has endured a frustrating summer in the transfer market after a succession of strikers turned down moves to the club.
Michael Owen, Marc-Antoine Fortune and Fraizer Campbell all opted for deals elsewhere, with Bobby Zamora set to become the latest player to snub the Tigers.
A £5million fee had been agreed with Fulham for the forward, but Roy Hodgson is expecting Zamora to stay at Craven Cottage.
Brown had been satisfied with the talks with Zamora and says he is pulling out all the stops in an effort to improve his squad.
"Of course I'm frustrated because I wanted to get players in and you want them in as quickly as you possibly can so you can work with them," Brown told the Hull Daily Mail.
"We need to be a bigger, better and stronger squad than last year.
"The first two weeks of our pre-season is all about fitness, but now we're to the football stage of that six-week period and you want the players in who will be playing for you next season."
Regarding his pursuit of Zamora, he added: "You do your business and hope that it falls right.
"The meeting with Bobby was positive and the communication with Fulham was positive. I can't do any more.
"You're in limbo and no man's land as a manager."
