Mikel Arteta says Arsenal have "put our stamp" on the Champions League with a 2-0 win over Paris Saint-Germain at the Emirates Stadium.
First-half goals from Kai Havertz and Bukayo Saka earned the Gunners a first victory in the revamped competition over the Ligue 1 champions, who finished as runners-up in 2020 and have twice reached the semi-final since, including last season.
