Manchester United manager Erik ten Hag refused to comment on referee Craig Pawson's performance in their goalless draw with Newcastle.
Pawson turned down penalty appeals from both sides and denied United a goal when Cristiano Ronaldo intercepted the ball when it was stationary, believing it to be in play.
Newcastle defender Fabian Schar rolled the ball to goalkeeper Nick Pope, the apparent kicker. Ronaldo intervened but to no avail and Newcastle's free-kick was eventually taken.
