Maguire believes criticism which is often so quickly levelled at the club is rooted in jealousy.
Some of the pressure which was building on Ole Gunnar Solskjaer after two defeats in four days - including the Champions League embarrassment against Istanbul Basaksehir - was lifted with a 3-1 win at Everton.
"At this club one thing I've noticed in my time here - I've been here a year and a half - is we are the most talked-about club in the world," he said.
"Why? Because we are the biggest club in the world. People don't want us to do well. Why? Probably because of the success we've had in the past.
"We have to live up to that, we have to react to it and don't let the negatives get into our bubble inside the training ground. Sometimes it is difficult for the lads."
