I don' t know if the draw is rigged.
The only thing I know is:
Barca's recent CL groups in contradistinction with Real's:
2018:
Inter Spurs PSV for Barca: a tough group
Roma CSKA Plzen for RM LOOOOL
2019:
Dortmund Inter and Slavia for Barca, group of Death
PSG, Galata, and Brugges for RM, only 1 strong opponent
2020:
Juve, Dynamo, Ferencvaros for Barca, easier with 1 strong team
Inter, Shaktar, Gladbach for RM, no top opponent but 3 tricky
2021:
Bayern, Benfica, Dynamo for us, 1 strong
Inter, Shaktar, Sherif for RM, no top 2 tricky
2022:
Bayern, Inter, Plzen for us. group of death
Leipzig, Shaktar, Celtic for them, cruising
So, in 5 recent seasons,
Barca had thrice a group of death (Spurs-Inter, Inter-Dortmund, Bayern-Inter now), once a group with a clearly superior elite opposition (Bayern) which meant 2nd spot is ceiling, and only once (vs Juve) a group where 1st spot was clearly achievable
On the contrary,
Real NEVER had a group of death,
Twice (2018 and now) EL-level group,
Twice (2020, 2021) a group where they were clearly favorites for 1st spot, and only them fucking up badly like in 2020) could cause them trouble
Only once (2019) a group with a strong side that could challenge them for the 1st spot
LEVELS between these draws...
