Zlatan Ibrahimovic will receive a tailor-made pre-season programme at Manchester United after skipping their tour of China.
Ibrahimovic is still on holiday following Euro 2016, where his Sweden side failed to make it out of the group stage, and will not feature in the International Champions Cup matches against Borussia Dortmund and Manchester City.
Mourinho insists his own analysis of the 34-year-old means he knows how to manage his preparation ahead of the new season.
He told reporters in Shanghai: “Suits made to measure should be better than going to a shop and just buying a size that may fit you well or not so well. I do the same for players. There are no two players the same.
“My decision on Zlatan is the consequence of many hours of study, analysis and discussion with my staff.
“Despite the fact he was out of the Euros one match before the English guys, everything is different. The body is different, the mind is different and the timing to have holidays and even things you don’t know, and don’t have to know, is to prepare in a different way like we do at training level.
“We try to do suits by measure that are perfect for the person and the way I’m building the team is more important for me with the players from other positions than the one I think who is going to play as the striker.
“I need to change the profile of the team in relation to other dynamics. The striker will be the easy one to finish the puzzle.”
United confirmed the signing of Ibrahimovic this month after prolonged speculation as to his next club once he outlined his intention to leave Paris Saint-Germain.
The former Inter, AC Milan and Barcelona striker may make his United bow against either Galatasaray on July 30 or Everton four days later in Wayne Rooney’s testimonial.
