Although Napoli failed to win the last two matches against Real Madrid, Napoli are quite optimistic about this match. The positive side for Napoli is that this match will be played at their home ground and they will have a full strength XI against Real Madrid which will motivate them to do well against Real Madrid.
Napoli are not as strong as they were in the last season and even Real Madrid became weaker too but I think a decrease in quality of Napoli is bigger than of Real Madrid. The recent forms are skewed into Real Madrid rather than Napoli and with bad face to face results of two clubs, Real Madrid is my choice for a winner.
Real Madrid is always a favorite for the Champions League. Real Madrid have been beaten in the first match of this season's Champions League and Real Madrid will be looking to continue their winning streak in the second match as well. In order to win this match against Napoli, Real Madrid's strikers must perform brilliantly and the defenders must hold the defense with responsibility, only then it is possible to get full points in this match.
They have Champions League DNA and they will not easily let Napoli to have a draw or three points because Champions League group stage is just at beginning. Real Madrid must play well and secure their position in the group and with this approach, Napoli will not have much chance to gain points. If they want to have points from Real Madrid, they must wait for a second match between two clubs.
