Watford are now in 19th place, four points off the top six, and Harley claims promotion is still the target.
"The start we've had isn't a fair reflection of how we feel we have done. We feel we should be higher," said the summer signing.
"As soon as the transfer window closed, we knew this is the squad we had to go on with and we believe it is as good as anyone else's. It's not a problem to us.
"Our aim before the season was to get promotion and that has not changed. It's not the start we would have liked but we still have belief."
