Arsenal title winner Alan Smith has praised manager Mikel Arteta for backing William Saliba.
Saliba scored in victory at Bournemouth.
Smith, who was on commentary during the game, said: "Saliba has been welcomed into the fold by the players and the fans.
"He would have gained a lot of confidence in France and especially making his debut for national team, when really he couldn't find a place at his club.
"He's come back, Arteta has shifted Ben White to right-back and we will see if that continues. Fair play to Arteta."
