The Reds were made favourites for League One as soon as the odds came out for next season and before boss Gary Megson had entered the transfer market.
That remains the case with the price unchanged at around 9/2 for them to win the League One title.
Bristol City are the clear second favourites. Their price was shortened after they signed Marcus Stewart from Sunderland although since then they have lost top scorer Leroy Lita to Reading.
Forest are around 6/4 to be promoted back to the Championship while ultra-pessimists's can have around 25/1 on a second successive relegation.
