However, Newcastle United, Bournemouth and West Brom follow shortly behind.
Sky Bet price Norwich City at 9/4 and Watford at 15/2. But Sunderland and Villa lead the way...
Both have endured torrid starts to the season, with Aston Villa currently bottom but Sunderland enjoying very little of their campaign outside of a 3-0 win over Newcastle.
With two wins in their last three, however, Newcastle boss Steve McClaren (above) will be a very happy man - and it's a far cry from when the St James' Park outfit were considered favourites to go down.
That unfortunate honour currently lies with Sunderland, while Villa are second in the view of the bookies.
West Brom have generally done well but several small runs of poor form keep them as outside bets. Whoever goes down, it's a battle that will likely last until the dying embers of the season.
