As the season progresses, Juventus continue to dominate Serie A with impressive performances on the pitch. In their latest round, they secured a comfortable win over Sampdoria, maintaining their lead at the top of the league.

The team's performance has been nothing short of exceptional. Their defense has been solid, allowing just two goals in their first four matches. This has given them ample opportunity to attack and score goals themselves. The midfield has also been efficient, providing the attacking threat that has been missing from previous seasons.

In terms of points, Juventus have already accumulated 12 out of a possible 15, which is a fantastic start to the season. They sit ahead of AC Milan by just one point and are looking strong for a potential title challenge this year.

However, despite their success so far, there are still some areas that need improvement. For instance, the team's defense needs to be more consistent, as they have conceded three goals in their last two games. Additionally, their midfielders could benefit from some additional creativity to help unlock opposition defenses.

Overall, Juventus' performance and points situation after round 4 is looking very promising. With continued focus on improving their weaknesses and maintaining their current level of performance, they are well-positioned to secure another successful campaign.
