The Gunners secured the victory thanks to goals from Ebere Eze and Leandro Trossard, with Eze scoring his first goal for the club.
Arteta noted that the game was challenging, as expected, due to Port Vale's reputation and the importance of the match.
He praised the team's dominant start, mentioning that they created several scoring opportunities, but struggled to convert them into goals.
Arteta acknowledged that the team lost some control in the second half, particularly with direct play and throw-ins, but made adjustments to regain dominance and scored a second goal through a beautiful combination between Willy Saliba and Leandro Trossard.
He expressed happiness with the win, clean sheet, and debut of goalkeeper Kepa, as well as Ebere Eze's first goal for the club.
Arteta also noted that the team's ability to perform well despite making nine changes was a positive aspect of the game.
He discussed the decision to give Bukayo Saka only an hour of playing time, explaining that it was planned to avoid overloading him after long periods of absence due to injury.
