Norwich chief executive David McNally says Norwich could move swiftly to replace manager Chris Hughton if their Premier League status is threatened. The Canaries are just two places and one point above the relegation zone, although they have a game in hand. They are also the only side in the bottom six not to have changed manager this season. "It would be almost delinquent of the football club to not be aware of potential candidates if for any reason your manager left," McNally told the Eastern Daily Press. "If results are not good enough you have to be aware of who is out there to help. You look at the market and who might be right for Norwich City. "If we needed to make a change - and the average tenure of a Premier League manager is about a year and a half, which puts Chris in the top six or top eight longest serving right now - then if a change was necessary it wouldn't be a case of, who are the contenders? "It would be a case of reviewing what is required, where are we going and who is best placed to take the club forward."
