Juventus are top seeds in the Champions League draw, while Napoli go into Pot 2.
Roma crashed out of the competition in the play-off stage, so there are only two Italians in the group draw on Thursday.

Juventus are among the top seeds as Serie A winners, along with holders Real Madrid, Barcelona, Leicester City, Bayern Munich, Benfica, Paris Saint-Germain and CSKA Moscow.
