Summer recruitment has seen six players arrive and three go out for a net loss of just Â£1m â€” but Hughes doubts there will be any further arrivals.
"We are in a position where we are quite happy with what weâ€™ve got," the Welshman said. "We canâ€™t guarantee we can have a transfer window like this every time but the chairman understands that.
"Weâ€™re trying to make the club better and get good players here, which I think we are doing.
"We wanted to spend the money but it has to be the right deal. If there are other opportunities we will pursue them."
