Jose Mourinho has admitted he landed a “difficult” job as Manchester United manager.
The former Chelsea boss took over from Louis van Gaal last summer and says he inherited a team “in trouble”.
United have not won the Premier League title since Sir Alex Ferguson retired in 2013.
Their highest finish since Ferguson’s exit was fourth place under Van Gaal in 2015.
Van Gaal also won the FA Cup shortly before he was sacked last May.
“There are no miracles in football,” Mourinho said while starring in a new film celebrating his partnership with Jaguar in Manchester.
“When a team is in trouble for two, three, four years, it’s for some reason.
“When a team win titles, and in recent years (don’t) win titles, it’s for some reason.”
United are 14 points behind leaders Chelsea this season and sit in sixth place with 16 games remaining.
Mourinho added: “Some people get more difficult jobs than others, I got the biggest job in the country, one of the biggest jobs in the world
“(It is) a job I can imagine everyone would like to have, but I got a difficult one.”
