Not trusting young players is a stick Mourinho has been beaten with since his first spell at Chelsea but a stat has been unearthed that will change your mind on everything you've heard about Rashford recently.
"I read something, some quote from the worst manager in the history of the Premier League, Frank de Boer saying it's not good for Rashford to have a coach like me", Mourinho said. "If he was coached by Frank, he would learn how to lose".
Speaking on BT Sport's highlights show on Saturday evening, De Boer had said: "It is a pity that the manager is Mourinho".
"Normally he's an English player, you want him given time, he can make mistakes".
"I think we deserved the goal and then it was the situation with the best piece of football in the whole game, the one-two between Roberto and Sadio and a clear foul and no penalty", Klopp added.
After all the discussion of whether Rashford is fading away under Mourinho at Man United, the Special One threw him a start against Liverpool and he kindly paid him back with a brilliant brace to win the staunch rivalry. I would say he was in the top five with more matches for two seasons.
With Manchester United having a crucial Champions League game on Tuesday against Sevilla, in which only a win will see Mourinho's side through to the quarter finals, Rashford will surely have helped his chances of starting that game after his masterclass on Saturday.More news: Mourinho: Anything is possible if United reach Champions League quarters

The 47 year took over the Palace job at the beginning of the season, after Sam Allardyce left at the end of last season, and lost all four of his first four Premier League games without the side scoring a goal before he was sacked. The best thing to happen is to have experience.
'Marcus is having these experiences.
"We want the supporters behind us, since I've been here they've been really good".
"Does he play every match from the start?"
'I am really pleased with everything. He's a player we trust.
After the academy product's performance vs Liverpool it will surely be easier for the Portuguese manager to include his player in more matches.
