Hodgson, who takes his Crystal Palace side to Old Trafford on Saturday, said “I'm afraid when you make mistakes that are as big a mistake as Mason Greenwood made you should be expected to pay some sort of price for that.
“So I'm not certain sympathy is the right word.
“It is important he learns from the mistake, I'm sure he will, but errors of that magnitude unfortunately are going to be criticised, scrutinised and are going to be punished I guess.
“I'm not prepared to stand here and say sympathy, I'm not even really prepared to talk about age as well.
“The fact is if you are old enough to come in and hold down a regular spot at Manchester United, and you are old enough to get called up and play for England then I'm afraid you've got to produce that level of behaviour that is required in those instances."
