After opening the Premier League campaign with a largely comfortable victory against Leicester, the Red Devils crumbled on the south coast last Sunday.
Their performance at Brighton was more of a concern than the 3-2 defeat and saw United come under the microscope, with intense scrutiny on the manager, players and background operations during an uncomfortable week.
Mourinho’s men have to wait until Monday for a shot at making amends and the United boss warned his players that they can ill afford to make similar errors against Tottenham.
The Portuguese said: “You know, just looking to Leicester and Brighton. Against Leicester we didn’t make mistakes, we played well, we won. Against Brighton, we made mistakes, we paid for the mistakes and we lost.
“So, I think you look at football in a very pragmatic way, normally you get what you deserve, so if we want to win against a good team against Tottenham, we cannot make mistakes.”

Mourinho, whose tetchiness in the pre-match press conference made ripples, cannot wait to be on the touchline on Monday.
United have a splendid home record against Spurs and come into the match after impressive training ground output.
“I think nobody is happy, obviously,” Mourinho told MUTV.
“But I have enough experience to know that in football you cannot look back for good results, for bad results and you have always to look to the next one. That’s our life.
“So, I’m really happy with the work we did in the week, with the players’ commitment and I look forward for the game. You can look at (having to wait until Monday) from two different perspectives.
“By one side I would say yes but, on another side, I would say we need time to work and some time to try to recover some players from injury, so it was not bad for us.”
United forward Alexis Sanchez, defensive midfielder Nemanja Matic and captain Antonio Valencia could all bolster Mourinho’s squad for the visit of Spurs.
Sanchez missed last week’s loss at Brighton through injury and will be assessed, just as Matic and Valencia will be as they push for their first minutes of the campaign.
Summer signing Diogo Dalot is also training as Mourinho looks to name a team capable of giving top-four rivals a bloody nose once more.
“That’s what we tried to do the last season,” he added.
“In big matches last season we managed to get lots of good results, which in the end are points like the other points in the other matches.
“But for the supporters normally it has a little different feeling.”
Alexis Sanchez, Nemanja Matic and Antonio Valencia are possible options for Manchester United’s
clash against Tottenham on Monday.
Sanchez missed last week’s loss at Brighton through injury and will be assessed, just as defensive midfielder Matic (abdomen) and captain Valencia (calf) have returned to training.
Summer signing Diogo Dalot (knee) is also training with Jose Mourinho’s men for the first time. Ander Herrera, Sergio Romero and Marcos Rojo have been United’s other injury issues.
Provisional squad: De Gea, Grant, Valencia, Darmian, Shaw, Young, Lindelof, Smalling, Jones, Bailly, Pogba, McTominay, Fred, Pereira, Fellaini, Matic, Mata, Lingard, Martial, Sanchez, Rashford, Lukaku.
Predicted Starting XI: De Gea; Young, Bailly, Lindelof, Shaw; Matic, Pogba, Fred; Rashford, Lukaku, Sanchez.
Sunday’s embarrassing 3-2 Premier League defeat at Brighton has left United reeling, with intense scrutiny on the manager, players and background operations this week.
Questions also remain over the happiness of Pogba, with his agent Mino Raiola this week taking aim at United great Paul Scholes for questioning the France international’s leadership at Brighton.
Pogba admitted his “attitude was not right enough” on the south coast, but Mourinho was distant when asked about it.
The United boss said: “If you want any explanation about Paul’s words you must get him and ask him.”
But getting a chance to speak to Pogba appears as easy as it was to get a straight answer out of Mourinho on Friday.
The United boss refused to talk in depth about Tottenham, despite having previously admonished journalists for failing to ask enough about the opposition.
Mourinho was perhaps most forthcoming when it came to the group’s reaction to the Brighton loss.
“Difficult is after the match you lose. (It) is always difficult, especially for people who really care about the job, about being football professionals,” he said. “But after that you think about the next match.
“You do the same when you win. When you win, you have to move on and focus (on) what (is) next. Imagine, when you lose you have to do even more.”
Yet not even the gradual alleviation of United’s injury issues could raise a smile.
The Portuguese added: “I don’t know because today is still Friday and training Saturday, training Sunday, match Monday.
“Decisions (are) to be made Sunday but yes (Nemanja Matic and Antonio Valencia are) training with the team. (Diogo) Dalot is also training with the team for the first time this week, so in terms of (the) medical department they are almost free.”
