Arsenal has scored a minimum victory on the trip to Brentford, within the 13th round in the Premier League.
The Gunners won with a minimum score of 0:1, thanks to a late goal by Kai Havertz.
Arsenal were generally the better team, having many chances, but they lacked the finish.
The much-criticized Kai Havertz turned out to be the hero, as he scored just eight minutes after the goal (88′).
Bukayo Saka miraculously darted inside the area to find the German, who found it easy to head home from close range.
After this victory, Arsenal now leads the Premier League with 30 points, while Brentford is ranked 11th with 16 points.
In the next round, Arsenal host Wolves while Brentford host Luton.
