Chelsea’s woes deepened as Brighton produced a brilliant second-half comeback to win 3–1 at Stamford Bridge, with Danny Welbeck the hero and a costly Chelsea red card swinging the derby’s momentum.

The Blues went into halftime 1–0 up thanks to Enzo Fernández’s strike, and the home fans sensed control. But the match unraveled after the break. Trevoh Chalobah’s dismissal left Chelsea exposed, and Brighton capitalized ruthlessly.

Mats Wieffer leveled the score just past the hour before substitute Welbeck struck twice in the closing stages, silencing Stamford Bridge and sending the Seagulls faithful into raptures.

Chelsea’s collapse leaves big questions over their discipline and mentality, while Roberto De Zerbi’s side celebrated a statement win powered by Welbeck’s clinical finishing and relentless pressing.
