Tbf, a lot of that is due to the luck they get. You look at the ghost goal that went for them but against Chelsea. Look at all the decisions that went in their favour vs man City.
Look at the way chelsea were treated when they outclassed barca in the semi a few years back, compared to how the RS got a lot of favourable decisions.
This is why I take no interest in the champs league, its based largely on luck rather than who's the best in europe. If it wasn't the case, why are two teams utterly miles off their respective league champions in the final?
The RS roma semi between two teams who have gone about 50 seasons combined without winning their own league and we're supposed to believe they're in the top 4 in Europe ha, the RS aren't even in the top 4 best teams in England.
