According to the Daily Mail, an FA investigation has uncovered that the forward admitted to Arsenal players that he could not keep the ball within the field before his cross into the box that led to Gordon's goal.
Willock chased down a shot by Jacob Murphy, which initially appeared to be heading out for an Arsenal goal-kick. But he persisted and managed to retrieve the ball, subsequently crossing it into the box. Within the chaos of the penalty area, Joelinton managed to get the ball to Gordon, who seized the opportunity and tapped it into the net amid a scramble involving Arsenal defenders and goalkeeper David Raya.
It was a turning point in the match as it was that particular bit of action which decided the fate of the match in Newcastle's favour.
