Saka converted a penalty against Tottenham in the second half by putting the ball past a diving Guglielmo Vicario and down the centre of the goal.
At Emirates, the 22-year-old's colleagues and him erupted in jubilation.
Their happiness, however, was fleeting as Tottenham quickly responded after Son Heung-min's second goal of the game was assisted by James Maddison, and the game ultimately finished in a 2-2 draw.
Neville thinks Arsenal's second goal came about as a result of their lack of concentration while celebrating Saka's score.
They all went to that corner when Saka's goal went in, according to Neville, who spoke to Sky Sports. "I don't want to get caught up in an Arsenal over-celebrating thing and argument here," he said.
They had to focus, turn on, and concentrate since they had work to do. Before the game had started, they were discovered. I don't believe it was appropriate to overjoy in that corner; rather, I believe it was appropriate to return to the midway point and realize that the game was far from over. Son has a nice ending," he continued.
