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.
While Barcelona being the favorite during the second leg should not surprise anyone that watched the first leg, at the same time it should be worrying that the only clear opportunity Napoli got ended up in a score, so Barcelona cannot attack recklessly during their upcoming match or Napoli could seriously punish any mistake they make on defense and get a surprising win that no one expected.
