Arsenal boss Unai Emery was relieved to have eventually put the Huddersfield game to bed as he cited a lack of rhythm in the performance.
The Gunners largely dominated proceedings and let several opportunities to move ahead pass them by.
Their increasing desperation was captured when Matteo Guendouzi was also booked for diving, this time having exaggerated a challenge inside the penalty area from Aaron Mooy.
It was then the impressive Guendouzi who created their winning goal.
Crossing towards Pierre-Emerick Aubameyang, he watched as the striker chipped to Lucas Torreira after struggling to get a shot away, teeing Torreira up to acrobatically volley into the bottom left corner of the near-open goal, maintaining their pursuit of the top four and leaving Huddersfield in the bottom three.
Emery, speaking to Sky Sports, spoke of how his side were unable to control the game but snatched the points. He said: “It was a tough match, like many matches, and today it is important because we didn’t have rhythm but still won.
“I’m very happy with the result. It was hard for us to control the match today.
“Patience is the key word today. I wanted us to win more quickly but we needed to be patient.
“We can improve more and today we spoke that we want to win matches with more control. But we are very competitive and showed character.”
