Maybe this is a problem of poor strategy for Napoli or because Barcelona is too good at managing the tempo of the game. Barcelona performed well from the first half and so far they have made 6 shots on goal out of a total of 11 shots. They can win this match and increase their chances of qualifying for the quarter-finals, so in the end perhaps this is why Barcelona should not be underestimated.
I agree if Napoli is lack of strategy. The hired Francesco Calzona who has no experience in managing a top club, he also has no experience as a player. The most experience of Francesco Calzona is just an assistant manager. I think his level isn't enough for UCL competition, he is more appropriate in domestic competitions. During the match, Napoli only made 1 shot on target from 6 total shots. It clearly indicated that Napoli still can't keep up Barcelona game.
The first leg was supposed to be a momentum for victory, Napoli actually conceded first even though in the end they were able to make the score equal again. In fact, Barcelona was also not at its best, but due to Francesco Calzona lack of experience, Barcelona was able to dominate the match. Barcelona's improving form will make it increasingly difficult for Napoli to play in the second leg. Barcelona is starting to find sharpness and will take advantage of the match held at Camp Nou to reach the next phase.
Barcelona's defense is also good. Araujo, Martinez and Kounde impressed, as did Joao Cancelo, but Barcelona still have to be alert because Napoli really don't want to lose at home. But now the score has changed, 1-1.
I don't think so. Barcelona defense looks weak, they got 1 conceded goal from 1 shot on target made by Napoli. If the defense is strong enough, they won't be easy to get a conceded goal at the match. Sorry, I think the defenders must improve their performance.
Of course, the defensive area is one that needs to be improved, Xavi must give direction to his players to build an even more solid defense. Raphinha has also started to be included in the Barcelona squad, in his last match he was able to score one goal and one assist, of course this is good news for Barcelona ahead of the match against Napoli.
