Arsenal turned a tense first half into a rout after the break, ripping Atlético Madrid apart in a furious second-half burst to win 4-0. Gabriel opened the scoring early in the half before a six-minute flurry sealed the game.

Myles Lewis-Skelly and Gabriel set up Martinelli for the second, then Ebere Eze’s volley deflected to Viktor Gyökeres for a scrappy third, and Gyökeres finished again from a Declan Rice set-piece to make it 4-0.

The result was a complete statement: a clean sheet at the Emirates, continued Champions League dominance under Mikel Arteta, a perfect group record and a 100-win milestone as Arsenal head into their next Premier League clash with swagger.
