I understand your criticism of Barcelona's performance. It has been kind of a rollercoaster, to be honest. Although they may not be as strong as they formerly were, I wouldn't write them off just yet. They haven't had a great UCL run, but luck isn't everything. Do you recall a few years ago when Chelsea won the Champions League? Nor were they the favourites. It all comes down to grasping oportunities. When Barcelona plays Napoli in the knockout stage, well, that's a break. It's an even playing field because neither team is precisely playing at their best. Barcelona has a good chance if they strenthen their defence. But let's face it, this will be a difficult game if their defence plays poorly. It all depends on how they perform that day.
Xavi Hernandez will be blamed if Barcelonw failed to win any major title this season, however the coach is looking forward to make new signings in the January transfer window and that have remained his initial plans to becoming more successful. The Champions League Barcelona found themselves, they will be eliminated if they don't take good time to measure the threats that will be posing from Napoli in the round of 16. Barcelona performance have been underrated because they lack the necessary qualities to continue pushing forward for good games and earning accumulated points.
