Hughes was in the Chelsea team the last time Stoke beat the Blues, in a League Cup game in 1995, while their most recent league win had come back in 1975.
Hughes said: "It was a great result for us. I thought it was a fantastic game. From start to finish we put in a real performance.
"We had to recover very quickly from the disappointment of going behind in the game. I thought we showed real character and we stuck at it.
"Chelsea gave us a little bit of a runaround in the first half and we had to hang on in there, but that's what we did.
"In the second half I thought we were excellent, and the two goals we scored were absolutely outstanding.
"It was another blow having got our noses in front to concede almost immediately. That was a test of character as well but we stuck at it.
"From our point of view it's a huge result because we've set our standards today and we need to maintain them."
