Chelsea were beaten 2-1 away by Arsenal, taking the lead through Morgan Rogers after just 77 seconds before Havertz and Odegaard scored twice in the second half to complete the comeback. The defeat ended the Blues' perfect start to the Premier League season.
A fast start did not bring three points.

Rogers gave Chelsea the lead in the 77th second of the match. Arsenal did not panic, with Havertz equalising before Odegaard completed the turnaround in the second half. The victory extended Arsenal's unbeaten run against Chelsea and kept them close to the top of the table.
James refuses to draw conclusions too early.
After the match, Chelsea captain Reece James did not make any sweeping judgments about the team's title chances. According to Fabrizio Romano, James said: "We will see where we are at the end of the season." He added: "We know what we have to do, we have to focus on ourselves and not let other teams distract us."
These comments reflect a Chelsea side that is still adapting. Alonso's team showed potential at the Emirates Stadium, especially in the opening stages and late in the match, but Arsenal's greater control and experience ultimately proved decisive.
Three matches are not enough to decide everything.
James' attitude is exactly what Chelsea need at this stage. After another expensive summer transfer window, it is natural for outsiders to question whether they are ready to challenge Arsenal and Manchester City, but making a final judgment based on only three league matches would be premature.
Chelsea showed enough quality against Arsenal to prove they can compete with the strongest teams. Rogers' early goal highlighted their attacking threat, while Palmer and Estevao also created dangerous chances late in the match. The difference was maturity — Arsenal did not panic after conceding early and gradually took control of the game; Chelsea still looked like a team learning Alonso's system and figuring out how to handle difficult periods.
This defeat is not a disaster. James was right that Chelsea's priority should be their own growth rather than focusing on Arsenal or Manchester City.
