Hughes offloaded 17 players during the close season while bringing in a dozen new faces, and has also been dogged by injuries, particularly in defence.
"I'm still learning about the group, still learning about the players I have," said Hughes.
"We had a big turnover in the summer and we all knew it was going to take time. Tony (Fernandes) is a very supportive chairman and I've got great support from the shareholders.
"We've talked and discussed what could happen at the beginning of this year because we all understand it may take some time.
"But we are all fully committed to what we are trying to do.
"It is disappointing because we have showed glimpses of what we can do but we haven't been able to sustain it for 90 minutes.
"That will come. We've just got to keep working hard and cut out the mistakes."
Hughes added: "We are struggling to get a settled unit. We are having too many changes and a number of players are still carrying injuries and are not 100 per cent.
"It would be great to have a full complement of players who could complete 90 minutes.
"At the moment it seems that we can't get to that stage."
