Bristol City manager Steve Cotterill has described the timing of the transfer window as a "nonsense" and a "nightmare".
The window is open from 1 July until 1 September, but Cotterill says it should have closed before the season started on 7 August.
City missed out on signing Dwight Gayle and Andre Gray this summer.
"It becomes a nonsense, it really does, dragging into the season," Cotterill told BBC Points West.
"I was as stressed as anyone in May and June because we did not sign anyone.
"You may as well have the stress then, rather than the stress of your team playing when the season starts also. You've got double.
"If you made it before the season started, everybody would know where they are.
"When you're not quite sure what you've got and you're waiting for a player to potentially come and join you, it's a nightmare situation for any manager."
Cotterill has not given up hope of adding to his squad before Tuesday's 18:00 BST deadline, but believes the loan market may be a more realistic proposition.
He said: "If there are players that don't want to join us, I don't think that's anything to do with the football club or me. That'll be purely down to finances.
"The money that is flying around out there, we are nowhere near it. These days if someone offers double what we offer, you are not going to sign for me."
