Saliba impressed as Arsenal strolled to victory. Gabriel Martinelli opened the scoring for Arsenal in the first-half, heading home after a well-worked corner routine.
Saliba spent sections of the last three seasons on loan in France after signing for Arsenal in 2019, returning to Saint-Etienne before spells at Nice and Marseille.
And he believes the match experience has served him well: “It helped me to spend three years on loan in France. I am young, I needed to play.
“Now I am back. I hope we will make a good season.”
Despite the ease with which he played, Saliba insisted he needed to put in the effort to impress for Arsenal on Friday. He said: “It’s never easy (to slot into the side). I have to give the maximum. It was good.”
Special report: Guendouzi is Arsenal’s past, but what about Saliba?
