There was no winner in the Napoli-Barcelona match. Napoli managed to draw with a terrible game at home.Barcelona has the potential to beat Napoli, but it seems that things are not going well for them either.At least it's a good enough result for Barcelona.They will win the next match at home and go through.
I didn't expect Arsenal to lose.I thought the match was very unpleasant because only 2 of the shots taken by both teams during the 90 minutes were accurate, one of which was a goal in the last minute.Arsenal, despite playing well, couldn't be very effective in front of goal against Porto and left with a goal in the last minute.Arsenal will have to show an extra performance at home now.
I agree with you that Barcelona will win against Napoli in the second leg of the UEFA Champions League Round of 16 matches. Napoli's performance against Barcelona was poor. Napoli just managed to have one shot on target against Barcelona, which led to a goal that earned them a draw. With Napoli's present form, it will be hard for them to beat Barcelona at Camp Nou.
I am still curious about the primary factor that allows Barcelona to perform even better than Napoli. It feels like napoli has been weakened. The current state of napoli is very different compared to the previous season. Napoli less aggressive and it doesn't have good defenders as well. It was putting napoli in very difficult condition caused by the club must be getting draw in the first leg. barcelona still owns the game till the second leg. I saw that the draw as a win for barcelona caused by it played away. Napoli needs to use the strategy that was being used by intermilan to beat barcelona. Barcelona was not that strong but napoli seemed even weaker compared to the barcelona.
This is also the main reason draw was happening in the first leg. The second leg is gonna be even more difficult, caused by barcelona has no choice other than try to create the big wall against barcelona. Napoli needs at least draw against barcelona.
