The on-loan Tottenham winger thumped home a stunning goal in the 2-0 triumph.
Pearson told Hull's website: "I thought John did very well. I don't like players getting booked for taking their shirts off, but I fully understand how excited he was and it was a fabulous strike.
"In many ways he was the difference because players who can produce that moment of brilliance win you matches. He showed both sides of his game and he worked exceptionally hard."
