Looking at the numbers, Chelsea may be the best attacking side in the league. They lead the way in expected goals (xG) at 22.5, shots on target per 90 minutes at 5.6, and big chances created with 39.

Chelsea are also high-volume passers, with 461.1 passes per 90 minutes at a success rate of 86.6%. This is a remarkable achievement, especially considering they aren't reliant on a single player. Joao Pedro, Pedro Neto, and Enzo Fernandez have all scored four league goals this season, with Moises Caicedo just behind them with three. This is a testament to the team's depth and balance.

However, it's worth noting that Chelsea have had a relatively easy set of fixtures so far, which may have contributed to their good numbers. They have faced some of the weaker teams in the league, including West Ham, Nottingham Forest, and Wolves.

One major challenge for Chelsea is their upcoming game against Arsenal, who are looking almost unbeatable at the moment. The Gunners have a strong defensive record, with an average of just 1.4 saves per 90 minutes. This will be a tough test for Chelsea, and it remains to be seen if they can come out on top.

In conclusion, Chelsea look good at the moment, but it's too early to say if they are true title contenders. They have a young squad that is still developing, and they will need to be consistent over the course of the season to challenge for the title.
