I'm pretty sure we'll be a team that is well organized and balanced. Benitez is quite methodical in his approach, and the training will be of a completely different quality than under Ancelotti.
We'll probably play 4-2-3-1 / 4-3-3. We will not see any tiki taka, but instead a team that is constantly trying to exploit the imbalance of the opponents. Something we do through a good defensive game, and this is something Benitez is a champion of. We will play quite directly, and the proportion of sideways passes and backwards passes will be drastically reduced this season.
I understand the skepticism, because I'm skeptical myself, but at least we get a coach who is obsessed with details, world class when it comes to organizing his teams, and who coaches his players unlike Ancelotti.
