Reigning Premier League champions Arsenal claimed a dramatic comeback victory over Chelsea at Emirates Stadium, winning 2-1 in a fiercely contested London derby.

Arsenal found themselves behind early in the match but showed the resilience of title-holders to turn the game around and secure all three points against their high-profile rivals.

Chelsea, who have invested heavily in their squad in recent seasons, pushed Arsenal hard throughout the contest — yet the Gunners proved too strong in the end, extending their reputation as the division's top side.

The result underlines Arsenal's credentials as Premier League champions and sends a statement to the rest of the division ahead of the remainder of the season.
