The Portuguese saw his side lose consecutive games against rivals Manchester City, Europa League opponents Feyenoord and Watford before returning to winning ways with the midweek EFL Cup success at Northampton.
Mourinho, a Champions League winner with Porto and Inter Milan told MUTV: “We had a bad week. I know that some football Einsteins, they tried to delete 16 years of my career and delete an unbelievable history of Manchester United Football Club and focus on a bad week and three bad results.
“But that’s the new football - it’s full of Einsteins.”
Mourinho, who began his Old Trafford career with four wins in a row, hopes to put the sticky spell behind him when he leads his team into three successive home games, starting with the Premier League clash against champions Leicester in tomorrow’s early kick-off.
“It’s always good to be at home,” he added. “I can understand completely the disappointment for the fans with the last week, but I’m sure, back at home, they will be behind the team like they always are.”
Ander Herrera hopes United’s “very bad week” was just a blip after ending a miserable run with a timely victory at Northampton. “Now we are going to think about keep winning games. We want to think it was a very bad week and now we can face Leicester in a different way, more positive.
“Hopefully we can win and we can keep being in the high (parts) of the table.”
Meanwhile Leicester boss Claudio Ranieri insists he has buried the hatchet with Jose Mourinho and any issues are “pr historic”. The Foxes go to Manchester United tomorrow with Ranieri and Old Trafford boss Mourinho having had a rocky relationship in the past.
Mourinho has previously criticised Ranieri for his achievements - before the Italian won the Premier League last season - and his use of English.
Ranieri has mainly remained quiet, but did defend himself in 2008 when he said he did not need trophies to be sure of himself.
But the Leicester boss said any problems are behind them and their history must remain in the past ahead of their second meeting in weeks after United’s 2-1 Community Shield win last month.
“Yes, but it’s prehistoric, not now,” he said. “It (their relationship) is fantastic, very good, no problems, why?
“Do you remember in the summer when we had the Soccer Aid, I managed the Rest of the World team against Jose’s English side.
“It (the issues) were a long time ago, I’m okay. All managers have a lot of jobs to do. It’s normal, he’s a great manager and a fantastic person. Maybe he has to offer me a good red wine. I love red wine and if he offers I will go and drink it with him (after Saturday’s game).
“Mourinho is a fantastic manager, intelligent, clever.”
Leicester are two points behind United in the Premier League, with Mourinho having lost three straight games in all competitions, including a derby defeat to Manchester City, before Wednesday’s 3-1 EFL Cup win at Northampton.
Mourinho has been chastised for public criticism of his players, but Ranieri felt it could be a ploy to get a reaction from his squad.
He added: “Every manager has his book, sometimes you need to do this. Sometimes, maybe not here but at another team, also I push to provoke the reaction of the player. There’s always a psychology. I don’t know what Jose did, so it’s difficult for me to say. Also, if I know I don’t tell you!”
Meanwhile, Leicester could be without goalkeeper Kasper Schmeichel after he suffered an muscle strain in training yesterday and will be assessed ahead of the game.
