Forest were the most favoured one according to bookies before the league phase draw started. But after it finished they've immediately gone down to the 6th favoured with 12.00 odds. 

Aston Villa are at the top with 7.00 for now. But I must add that they've started the PL horrible... Currently one of the worst teams there. If they don't recover I won't think the same as bookies to tell the truth.
