Norwich City goalkeeper Mark Bunn is wary of losing his place to fit-again England international John Ruddy.
Ruddy's comeback will present manager Chris Hughton with a selection dilemma.
"The main thing is the clean sheet. John's fit in a couple of weeks so I'll just keep working hard," said Bunn.
"I was a bit disappointed letting in four against Man Utd but I've been delighted with my form."
