The striker showed that a series of niggling injuries haven't made him lose his goalscoring touch.
First, the former Crystal Palace man beat Andreas Christensen to a long ball and set his side on the attack.
It was far from a flowing move as the ball ricocheted from player to player before being prodded back towards his own goal by Marcos Alonso.
Jacob Murphy almost seized on the ball, forcing Courtois into a save but the Belgian could do nothing about the loose ball, with Gayle on hand to fire Newcastle ahead.
