In the first round of Serie A, Fiorentina faced off against Sampdoria at home. The match was played on Sunday, August 16th, and ended with a disappointing 2-1 loss for Fiorentina. However, the team did not give up easily and made several tactical adjustments to improve their performance.

The first change that Fiorentina made was to switch from a 4-2-3-1 formation to a 4-4-2 formation. This move allowed them to create more space and control the midfield, which led to better possession and passing accuracy. The changes were effective as Fiorentina created more chances and eventually scored two goals through Dusan Vlahovic.

However, the second change that Fiorentina made was even more significant. They switched to a 5-4-1 formation during the second half, which forced Sampdoria to play more defensively. This strategy proved to be successful as Fiorentina dominated the ball and limited Sampdoria's opportunities to score.

Experts have praised Fiorentina's tactical adjustments and believe that they will help the team improve their performances in future matches. They also suggest that Fiorentina should continue to experiment with different formations until they find the one that best suits their style of play.

Overall, Fiorentina's tactical adjustments in the first round of Serie A showed that they have what it takes to compete at the highest level. With some further experimentation and improvement, they could become a formidable force in Italian football.
