The Portuguese, who was named as Eric ten Hag’s successor last week, will take charge of Sporting’s final home game as City visit the Estadio Jose Alvalade in the Champions League on Tuesday.
The 39-year-old accepts expectations will be high when he takes over at Old Trafford later this month and admits they could rise if Sporting beat City.
“I don’t think about it,” Amorim said at a news conference.
“My focus is to win the game for Sporting. The conclusions are not important to me because they can be wrong. If we win tomorrow, they will think the new Alex Ferguson has arrived.
“This will be very difficult to accomplish. It can raise expectations. I don’t think about that.”
