Pennant's goal was the highlight of a frustrating match that dominant Stoke should have won more comfortably with Kenwyne Jones, Marc Wilson and Jonathan Walters failing to convert first-half chances.
"I think everybody would agree that we deserved to win," said Hughes, who is hoping to bring in an attacking player before the transfer window closes on Monday.
"From the first minute until the last we got the ball down, passed and moved. Overall we always looked a threat and the only criticism I'd have is we should have won more comprehensively.
"We had to wait until the latter stages of the game and that great finish from Jermaine, but from our point of view it was almost the perfect away performance."
