Tottenham keeper Heurelho Gomes placed the ball on the floor expecting a free kick following a handball by Nani, the winger then ran up to the ball, looked around and slotted it into the net.
But Clattenburg allowed the goal to stand as he had not awarded a free-kick, meaning that the ball was active from the moment Gomes had put it on the floor.
Wiley, who now coaches the 16 select match officials as part of his role with the Professional Game Match Officials, believes Clattenburg did the right thing.
"First and foremost, what we have to remember is that the goal is within the laws of the game," he said.
"The game hadn't stopped and so, in essence, Mark was right in law.
"You're taught right from the very start that you don't stop until the whistle blows or the ball goes out of play, so in law the goal is a correct goal."
