Hughes takes his side to the north east this weekend looking to continue the misery for Keegan although he feels, given time, the Newcastle boss will effect the change necessary.
"There has been a fantastic reaction off the field but maybe that has not transferred as yet on to the field of play in terms of performances and results, which haven't gone the way they would have liked," said the Rovers manager.
"Kevin knows the club very well, better than anyone, and he knows what it takes to turn that around and he will be given time, which maybe any other manager wouldn't have been.
"At the moment it is a little bit difficult and there is a lot of focus and attention on the club and the team but really that is their concern and not mine.
"I think they have struggled with injuries to players Kevin would have liked to have called upon but it is difficult to come in and have an immediate impact on the style of play.
"You can have an impact on what's happening in and around the club and there can be a goodwill factor towards you but, at the end of the day, you still have to get results whoever you are."
