The Italian Serie A club Fiorentina is currently facing some tough competition in the Premier League, with teams like Manchester United and Liverpool posing a formidable threat to their chances of success.

One area that needs improvement for Fiorentina is their defensive strategies. The team has struggled this season, conceding goals at a high rate and failing to keep opponents at bay consistently. This has led to several defeats for the club, as they have been unable to secure victories against stronger opponents.

To overcome these challenges, Fiorentina will need to make changes to their defensive tactics. They may need to focus on improving their discipline and work ethic, as well as developing more effective defensive strategies. Additionally, they may want to consider signing new players who can provide them with additional cover and support on the backline.

Overall, it's clear that Fiorentina needs to improve their defensive strategies if they hope to compete successfully in the Premier League. By making the necessary changes, they could be able to turn things around and establish themselves as a serious contender for silverware.
