Erik ten Hag says he understands Cristiano Ronaldo's reaction to his substitution in Manchester United's goalless draw with Newcastle.
Ronaldo was the only United player to be substituted in the 72nd minute for Marcus Rashford and shook his head at the decision.
Rashford had United's two best opportunities but passed to Fred from an acute angle and nodded wide from Casemiro's cross in the 95th minute.
