The Red Devils boss has been lambasted by the media this season after ‘parking the bus’ against bigger teams.
Mourinho was extremely defensive against Liverpool in the reverse fixture earlier this season.
And United sat off Manchester City during their 2-1 defeat at Old Trafford in December, a result which has went a long way in shaping the Premier League title race.
But Mourinho wants members of the media to remember their own experiences before criticising his decision making – with a swipe at the likes of Neville and Keane.
“Some of the guys with an opinion couldn’t resolve their own problems when they were managers,” he said.
“So they are giving opinions like they have, solutions for everything but it is not like that but they are in a position where they can give opinions about everything.
“Sometimes I read, sometimes i don’t, sometimes I listen, sometimes I don’t.
“This week I was more focused on enjoying Champions League and Europa League and preparing my match than to be focused on opinions.
“But of course everyone has opinion.”
Mourinho’s side will be in high spirits after their impressive win earlier this week.
United came from two goals down to beat Crystal Palace on Monday evening.
And Mourinho wants the fans to once again provide much needed support when Liverpool visit.
“It helps,” he added.
“Crystal Palace I can imagine if we are losing 2-0 and our away fans, how many? 1,500 or something like that or 2,000?
“We could feel disapproval or criticism or support.
“It was 2-0 down and we only felt support and at 2-1 we kept feeling more belief and at 2-2 we felt they want us to go for it.
“They can help.
“Of course, Old Trafford is a huge majority of Manchester United fans, so they can help.”
