But while the Glaswegian's departure was a blow, Ruddy admits Hughton's arrival may be just what Norwich need.
On his new manager, Ruddy said: "He seems very good to work for. He knows what he wants. He's brought a fantastic backroom staff with him as well. I can't wait for the season to get started.
"Regardless of whether the old manager stayed or not, the levels would have to have been maintained.
"With a new manager coming in it probably helps us in the sense that that second season syndrome might not be there because we're all eager to impress him as well.
"It's a clean slate for everybody so everyone is starting a fresh."
