I think we should give the league first priority this season. With our defense we need extrem luck to Even reach the semis. We can win the lead.
Barca never puts any other competition above Liga. We'll see how seriously Tata takes Copa.
Any team can get knocked out in any round of CL eliminations, each underdog has at least a 10% chance. That's why the best team does not always win CL.
Out of all the group winners, Barca clearly drew the toughest first round opponent. I'd give City about a 30-40% chance of knocking out Barca, mainly because they could certainly win big at home.
