Smith-Rowe put in another good showing as Arsenal beat Newcastle 3-0 on Monday night, setting up the second goal with a dizzying run before squaring for Saka.
And speaking afterwards, Arteta heaped praise on the 20-year-old, saying Smith-Rowe and Saka deserve the plaudits coming their way.
“When we are winning, they put a smile on my face,” he said of the young pair.
“I know what they are capable of doing. They are developing really well, and that’s a merit to them, a merit for their team-mates and everybody that is involved to try to support them and protect them as well.”
