Arsenal struck four times in a blistering 14-minute spell to thrash Atletico Madrid and maintain their perfect Champions League start.
After a tense first half, Gabriel Magalhães broke the deadlock with a header from Declan Rice’s free-kick in the 57th minute. Gabriel Martinelli added a second before Viktor Gyökeres ended his goal drought with two quickfire strikes.
The Gunners have now won all three of their group games without conceding a goal.
