Their game against Inter Milan was good even though it was draw. In football high expectations mostly cause disagreements and while some fans might call draw poor you are right that sometimes luck just is not there even when team plays well. Your excitement for next season is obvious and it is great you expect them to win both Champions League and La Liga. With team actively getting stronger it id certainly fair to think they will play better than last season and if they can use their strengths and new players well we could definitely see Barcelona aiming for those top titles.
