Manchester United's interim manager Ralf Rangnick has been warned he cannot 'babysit' Cristiano Ronaldo at Old Trafford.
The comments by former Tottenham Hotspur boss Tim Sherwood were made in response to his reaction to being substituted at Brentford on Wednesday night.
Ronaldo was replaced by Harry Maguire on the 70th minute mark and he chucked his coat to the ground as he made his way to the bench.
