Mourinho suffered the biggest home defeat of his career with Monday's 3-0 defeat to Tottenham, meaning United have now lost two of their first three Premier League games for the first time since 1992.
Yet, Mourinho surely knows United is in a hole.
"It is a massive victory for us and I am very proud of the performance", Pochettino said.
There were some eye-opening comments after the loss to Tottenham, highlighting the identity crisis that might be enveloping United.
Mourinho switched up his tactics for last night's game against Spurs, deploying Ander Herrera in an unfamiliar position of right centre-back, with Jesse Lingard in a free role behind Romelu Lukaku.
Eric Bailly was not even on the bench against Spurs, Victor Lindelof came on for the injured Phil Jones and made a series of mistakes and Chris Smalling, who had made a key tackle in the first half to deny Dele Alli, was left standing by Lucas Moura for the third goal. "I care more about the result and as a team".
'We have a really good group and yeah of course we'll reflect on our day off (on Tuesday) and we'll come back in on Wednesday.
Mourinho, 55, remained on the pitch to applaud fans after the game at Old Trafford and praised them in TV interviews.
His dark mood has continued into the season.
And then, repeating the word "respect" over and over again, he was gone.
José Mourinho retains the backing of the Manchester United board despite overseeing their worst start to a season in 26 years.
"There are many circumstances that can affect this and it is not always under our control. You can see it. Jose Mourinho looks unhappy when this should be a dream job for him", Redknapp told Sky Sports.
Is Mourinho even sure anymore?
Jose Mourinho's side find themselves falling under mounting pressure just two games into the 2018-19 campaign. Previous year though saw United go an entire season without silverware, a rare occurrence for such a proud club.
"A team that fights the way they did with the solidarity between the players, it is clear the team is united".
United's defensive wall is cracking. He also added an FA Cup, Community Shield and three League Cups during his tenure in West London.
