I personally think that maybe Napoli can do better this time. They haven't been regularly joining the Champions League above all else. Therefore there was some lack of experience. They still did great last season of course. Because they made it to the quarter finals. However they couldn't deal with Milan obstacle despite a big effort.
But this time I will be expecting an even more competitive and aware team. They should be able to develop better strategies against especially the experienced teams of the tournament. When it comes to their group now I can just say it is quite easy for them. We should be watching a tough fight between Napoli and Real Madrid for advancing as the leader.
Im frustrated by Napoli's chances this time. Why? Madrid is in their group. Im not ignoring Union Berlin and Braga, but this is about Real Madrid. Last season, Napoli reached the quarterfinals but lost to Milan. I wonder if they can handle Madrid mentally. While everyone is talking about how tough Group F is because PSG and Manchester United play better clubs and Bayern Munich, Im focused on Napoli. This time, what will happen? However, Napoli's group isnt as insane as Arsenal's because they face Sevilla.
You shall not feel worried about that, madrid sees napoli as the strongest opponent in the group. Napoli and real madrid have the biggest chance to go to the play off stage. Braga and union berlin may not be strong enough compared with napoli and madrid yet these clubs need still to be careful with it. The chance owned by madrid and napoli are very big. Sevilla looks very weak. Arsenal was lucky enough to be in the same group with sevilla. You must also see if sevilla got zero points in la liga.
Sevilla is not as strong as before. Many players are leaving from the club. Mendilibar has no lots of choice to build a proper squad. Arsenal can pass the group stage easily as long as it will always consistently winning the game.
Arsenal's group was not as hard as you think. The gunner has a bigger chance to be on the top of group classement.
