Arsenal boss Mikel Arteta admits he's been pushing William Saliba to shoot more.
The defender scored in victory at Bournemouth on Saturday.
Arteta said, "We've been training that all week!
"It very much surprised me. Individual talent, a moment of quality - I don't know how you're going to call it but I don't think anybody expected it and it was great.
"I'm so happy for the boy."
