I'm not much positive about Barcelona's chance to eliminate Napoli honestly. Because their game is just not good enough. I believe that they haven't faced a real challenge yet. Porto were the second strongest team in the group but Barcelona won against them twice anyway. But I think Napoli are a bigger challenge than Porto for them.
Napoli have a stronger squad in the first place. They have a very dangerous player like Osimhen in their offense line. They are just trying to improve their form lately. But until this matchup I think Napoli will be in a better shape than now. If Barcelona don't make improvement at the same time then they can really say goodbye to the CL early.
But I think Barcelona was lucky during this season of the Champions League because we know they are not in their best form and this Barcelona we currently see can definitely lose games easily against other teams. While Barcelona is also not in the form to face with stronger teams, however Napoli has players like Osimhen as you just said and since Barcelona's defenders are weak this can be dangerous.
Both teams are currently facing problems with we still have 7 weeks in this first leg match and few changes can create difference with I have feeling despite many challenges Barcelona is much better team from these two in this match and have enough chances to qualify for the next round because Napoli is having problems which can create some mess-up in this transfer window and if they lost their any good player then most chances they could be down in domestic league and their golden period is going to end for another long time.
There will be so many problems to come for barcelona soon. Im not expecting this club to survive till the next stage. Barcelona is having too many problems that is very hard to be solved. This must become the main concern by xavi as the main coach of barcelona.
Im not complaining about the way he was coaching the club but there have been many factors that were also affecting the performance from the club. Barcelona will be missing some of its key players and this is another disaster for the club.
Barcelona needs to do something to fix it.
Barcelona is also in problems, but their coach Xavi is having enough sources to settle things and increase performance level which can bring better results for them in coming days, and they can go through for the top four and also having good chance for the top eight spot in this event.
Source for what? Does xavi has money to solve the problem owned by barcelona? Has the debt paid off by the club? This is the main problem that is always disrupting barcelona. As long as barcelona will always be in the huge debt and it will always become the main problem owned by the club.
Xavi needs to work even harder to fix it. The main problem is related to the financial owned by the club. Barcelona has very big debts and this is also making xavi to work even harder to fix it.
