Reigning Premier League champions Arsenal came from behind to defeat big-spending Chelsea 2-1 at Emirates Stadium, with Kai Havertz and Martin Odegaard among the standout performers. The result left Arsenal with nine points from three games and just one goal conceded, reinforcing their position among the title favorites despite not signing a new striker. Chelsea's defeat, despite roughly £349m spent in the transfer window, raised fresh questions about squad balance after the club ended the match with two right-backs playing alongside each other in midfield.
