After PSV Eindhoven goalkeeper Jeroen Zoet made the save, he made a costly mistake.
Zoet saved a close-range header from Feyenoord defender Jan-Arie van der Heijden, but after holding the ball up on the goal-line, he inexplicably dragged the ball back into his arms and into the goal, across the line by a hair's breadth. A screen on referee Bas Nijhuis' wrist lit up.
Nijhuis looked down, saw the word "goal" flashing on the screen and awarded the Dutch league leaders the winning score in a 2-1 victory. Sunday's result took Feyenoord a step closer to its first league title since 1999 and likely ended two-time defending champion PSV's title aspirations.
