Yes, Barcelona plays faster at home, but OLY will surely try to play slower and prevent Barcelona from running. They did it past few years and will do it again. During last three years, Barcelona scored more than 80 once against Olympiakos. During this season still no team managed that. Public seem to think it's Barcelona's time to win, as the line moved pretty hard for Euroleague game. And it might be so, but this O/U line for Barcelona is now against all odds.
