"I thought it was a great result, and with a clean sheet again. I thought we were excellent and performed extremely well against a good side," said the former England manager.
"David Nugent did very well on his return. He has been away for a month and today scored a goal and might have had more. He and Vassell were both very good, in offence and defence.
"The first half was one of the best we've had this season, along with our first half against Forest, and I hope we can go on like this."
The result has lifted Leicester into eighth place in the Championship table, a point off the playoff places.
