Chelsea, who play Crystal Palace on Saturday, are in contention to succeed United as Premier League champions in a title fight with Manchester City and Liverpool.
United are in seventh place entering this weekend’s fixtures as David Moyes, the man Ferguson hand-picked as his successor, endures a tough first season in charge.
Premier League chief executive Richard Scudamore this week suggested an under-performing Manchester United was bad for the competition.
Mourinho, who returned to Chelsea after a near-six-year absence last summer, contends there are other damaging aspects for the Premier League as he once again railed at the performance of referee Chris Foy in the controversial defeat at Aston Villa.
“There are lots of things that are bad for the image of the Premier League,” Mourinho said.
“A performance like Mr Foy is not good for the Premier League. Players cheating is not good for the image of the Premier League.
“We have only two teams in the quarter-finals of the Champions League. It’s bad that we have no teams in the Europa League.”
Like Chelsea, United are in the last eight of the Champions League.
