Manchester United boss, Jose Mourinho has admitted that tutoring the red devils is a difficult job.

Mourinho said “There are no miracles in football, 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,” Mourinho added.

The former Chelsea boss noted, “Some people get more difficult jobs than others, I got the biggest job in the country, one of the biggest jobs in the world.”

United have not won the Premier League title since Sir Alex Ferguson left in 2013.
