The Champions League group stage draw almost never results in the kind of pairings we dream of. A lot depends on the teams in pots 3 and 4 if you are looking for a bonafide group of death. For 2020, the danger lies in Inter, Leipzig and Atalanta amongst the pot 3 teams. I am not so sure about Lazio with this being their first season back after quite a while. As for pot 4, you really have to stretch — Gladbach, maybe? Rennes are leading Ligue 1 right now with an exciting team but its their first foray into the Champions League, while Marseille have the history but are unlikely to strike fear amongst the favourites.
