Mikel Arteta praised the "empathy" of his Arsenal players after a first goal for Kai Havertz that he hopes will "change everything" for the forward.
The £65m summer signing from Chelsea had not registered a goal or assist in his first nine games for the Gunners but finally hit the target as he converted a penalty in a 4-0 victory over Bournemouth at the Vitality Stadium.
When the Gunners were two goals to the good, Ryan Christie clattered into Martin Odegaard in the box as Bournemouth gave away their second penalty of the game.
Bukayo Saka, Arsenal's regular penalty taker, had already given the ball to Odegaard to convert the first spot kick.
