Never say never when it comes to football. If Napoli were able to win the league trophy last season tell me why it is impossible to win it this coming season with the recruitments they have made to further improve their team. I think it is very possible, their team looks very organized and stronger for next season.
Napoli will have a lot of busy schedules and that will affect their performance. Unlike, last season that they were only focused on Sera A competition. This is one of the reasons why I don't see them capable of winning the Scudetto back-to-back. Fatigue and injury will always play their own role on the players. Napoli was lucky last season that none of their key players was injured.
Last year, sorry, last season, we can say that he managed to win by using luck and taking advantage of Inter's mistakes. This year, we don't know; it could happen the other way around. Another team could be waiting in second place and steal the title from him at the last minute. Last year, it seemed like Inter would win everything, and instead...
Inter, having failed to play well in their recent matches, lost the Champions League final and the Scudetto. They had played very well throughout the league, but they couldn't finish the game as they wanted. They suffered a heavy defeat in the Champions League final, and that defeat led to their manager leaving the team. Now Inter is moving forward with a new coach. There are major question marks about what they can do this year. No one is certain of Inter's capabilities right now. I think they will be in the title race, but they may not go far in the Champions League.
