Roma got a boost for the Champions League group-stage draw when Basel crashed out in the second qualifying round on Wednesday.
Basel had been penciled into Pot 2 based on their UEFA coefficient, but the Swiss club still had to come through three qualifying rounds to reach the group stage, only to fall at the first hurdle, 5-1 on aggregate to Greek side PAOK.
Roma, as the top-ranked team in Pot 3, will now move up to Pot 2, giving them a chance at a more favourable draw in the group stage.
The result could also help Liverpool, who are ranked one spot behind Roma and can still move into Pot 2 if Benfica fail to make through their two qualifying rounds this month.
Also eliminated were Bulgarian champions Ludogorets Razgrad, who had been set for a place in Pot 3 but fell to Hungarian champs MOL Vidi 1-0 on aggregate.
That means Dutch champions PSV Eindhoven will now be in Pot 3, should they get through the final playoff round.
Provisional group-stage draw pots (*denotes must come through qualifying)
Pot 1: Real Madrid, Atletico Madrid, Barcelona, Bayern Munich, Manchester City, Juventus, Paris Saint-Germain, Lokomotiv Moscow
Pot 2: Borussia Dortmund, FC Porto, Manchester United, Shakhtar Donetsk, Benfica*, Napoli, Tottenham Hotspur, Roma
