The Portuguese has been tasked with making United a dominant force again after three years of failure under David Moyes and Louis van Gaal.
“It is strange to see him managing Manchester United," 80-capped France ace Malouda told The Sun.
“But I always wish him the best because he is a very good person.
“I know he wants to be successful and I think he is at one of the top clubs, where he always should be.
“He should never have left a top club like Chelsea but that is the manager's life.
“United is a big institution, a club designed to win. There was the Sir Alex Ferguson era. Everyone knows about that.
“The transition was difficult after him, which you can easily understand. But with Jose Mourinho they have someone with a notion and the capacity to bring it back to where they should be.
“They have top winners from the management through to the players. People with great character. They are not scared of pressure and maybe that is what was missing.
“When you see the players United have brought in they are winners. With Zlatan, you must respect what he has done in France.
“They will be very dangerous this year in the Premier League."
