However, they are no longer the favourites to win the title with Sale Sharks shortening from 8/1 to 4/1 after completing the signing of England powerhouse Manu Tuilagi.
Steve Diamond's side have won eight of their 13 matches, which includes a 22-19 win away at Sandy Park in December.
Bristol Bears are long-shots to win the Gallagher Premiership at 12/1, which comes as a surprise considering they're just two points behind Sale in the table.
Northampton Saints are 15/1 and Wasps are 20/1 respectively while Bath are a tempting 30/1 to finally win their first Premiership title.
