At Emirates Stadium, Arsenal met an early test of character when Chelsea's £117 million signing struck within 77 seconds, threatening to unravel a perfect season. Rather than fracture, the reigning champions answered with the composed resilience of a side that knows how to carry the weight of expectation. Goals from Havertz and Odegaard completed a 2-1 comeback, leaving Arsenal alongside Manchester City as the only unblemished sides in the Premier League — a reminder that true championship quality is often revealed not in the moments of ease, but in the moments of doubt.
