It's great that Juventus have been meeting other strong clubs and getting a point from them but couldn't do the same when they met Napoli and this should be like a warning to Thiago Motta to buckle up because the other clubs won't wait for them to pick themselves up and it's sad that even in the champions league, they still perform so poorly. Seriously, I can't really put a pin on what seems to be the problem because at the beginning they were the team that looked like they could give the other big boys trouble and I began feeling that they deserved to do well since last season was sort of a rollercoaster for them but they got their first draw and that was where the draws began and to an extent if you put the game to end in a draw, the odds don't always look attractive.
Napoli was on a mission to stain Juventus unbeaten record

. Just has you stated Thiago Motta just have to work on strengthening his teams attack. Juventus had the best of the game possession and also controlled the game play but had lesser chances than Napoli. If Juventus can create enough chances during their games they will have enough goals to win their matches other than struggling with draws in which their last game changed their draw records to recording their first defeat this season.
The champions league is a different tournament all together and I believe that is why Juventus is having difficulty coping. This season the structure of the tournament changed a little and we can use that as excuse for some teams because we also saw bigger clubs struggle with the new structure. I believe Juventus will qualify for the round of 16 but I don't know how they will deal with their attacks and ensuring the score goals that will guarantee them winning.
Seriously, it's like a trend. Start the game with enough pressure to frighten the opponent then when they just make one attempt, you turn tail and run. Napoli had more of the shots and attempts and Juventus could only come up with 5 shots over all whereas Napoli had 14 and 3 on target. Today they meet benfica where it would be the last game before they enter the round of sixteen and let me see whether Juventus will joke with this and be hoping for a draw because with how Benfica performed against Barcelona in the last UCL, I see them getting ready to not give Juventus breathing space.
