Goalscorer Giroud was under no illusions about just how hard-earned the three points had been.
“Honestly, we were not surprised to face this team because we knew their qualities," Giroud told Sky Sports.
"We conceded early and wanted to bounce back straight away. They were one of the best teams I have faced since a few months. Physically they run everywhere. It was so hard.
“It's a great feeling to win tonight because they drew against Man City and lost just to Liverpool. They really impress me. They are a good team."
