A contest that may not catch the eye to many casuals, but for the tactician lovers this may be the game for you! Napoli will be making sure this fixture is as tough as possible for Arsenal. From the amazing atmosphere of the Stadio Diego Armando Maradona, to the hard to beat style of Allegri. They will be on Arsenal's toes from minute one. Regrettably, Napoli come into this game sitting in an unwanted 12th spot within Serie A. Winning 0-2 away on the opening day against Genoa was a positive start for them, but a 1-2 home loss to Como, followed by a late capitulating 3-2 loss at the San Siro has surely downed the mood within their camp. Allegri will be looking to put things right here with a good performance and result, the fans expect big things at such a giant club. Napoli have a bit of an injury crisis as of late, with star player Scott McTominay set on the sidelines until after the international break. Injuries to Alessandro Buongiorno, Giovane and Luca Marianucci are not what Allegri wanted to see coming into the start of the Champions League campaign. On the other hand, Arsenal have began the season flying with 3/3 wins so far, scoring 6 and only conceding 1! Valid arguments could be made that their squad is much improved from last season, bringing in quality such as Bruno Guimaraes and Ezri Konsa for depth, as well as Christos Tzolis looking sharp coming straight into the starting XI. Mikel Arteta will know that Arsenal will be forced to dominate the ball here, with Allegri almost telling him "come on, try to break us down", but Arteta has learned a lot over the years, he seems to have ideas for everything. Cristian Mosquera and Jurrien Timber are big doubts for this tie, with William Saliba still suffering from an injury until at least the start of the new year. The last time these two sides met, Arsenal came out on top, with a 0-1 away win (0-3 agg.) in the 2018 Europa League quarter-final, a goal from Alexandre Lacazette to seal the victory for the Gunners. Their last Champions League meeting was in the 2013/14 Group Stages, where Arsenal were 2-0 victors on the night, early goals from Mesut Ozil and Olivier Giroud made sure of that. Full confidence for Arteta's team. Will pressure build on Allegri early? The Partenopei are not always patient, but perhaps they may see this as a free hit to get a performance right rather than dwell on a result.
