Fiorentina has made significant improvements in its performance this season as a result of its tactical changes during the first round of Serie A. The team's transformation can be attributed to the strategic adjustments it has made under the guidance of new coach Vincenzo Montella.

The first round of Serie A was crucial for Fiorentina, as it provided the team with an opportunity to showcase its new tactics and strategies on the pitch. The club's management and coaching staff worked tirelessly to develop a game plan that would allow the team to dominate on the field and gain an advantage over its opponents.

As a result of these efforts, Fiorentina's tactical changes have had a noticeable impact on its performance. The team has been able to create more opportunities for itself, which has allowed it to score more goals and win more games than it did last season. Moreover, the team's defense has also improved, making it difficult for its opponents to break down Fiorentina's defensive line.

One of the key factors behind Fiorentina's success in the first round of Serie A is the way in which the team has adapted to different playing styles. Under Montella, the team has adopted a more attacking approach, with a focus on creating space and exploiting the gaps between opposing teams' defenses. This strategy has paid off, as Fiorentina has scored more goals than any other team in the league so far.

Another factor contributing to Fiorentina's success in the first round of Serie A is the team's ability to adapt to different situations on the pitch. In one match against Juventus, for example, Fiorentina played a counter-attacking style, while in another match, it played a more structured defensive game. By adapting to different playing styles, the team has been able to find success both defensively and offensively.

Overall, Fiorentina's tactical changes have had a positive impact on its performance in the first round of Serie A. The team's new tactics have helped it to create more opportunities for itself, defend better, and score more goals. As the season progresses, it will be interesting to see how Fiorentina continues to perform under Montella's leadership.
