Mourinho became Manchester United manager in the summer of 2016.
He brought in Paul Pogba for a then world-record fee of £89million and splashed out big again a year later on striker Romelu Lukaku for an initial £75m.
Hutchison has questioned why Mourinho has not been able to improve Pogba and Lukaku as well as Marcus Rashford and Anthony Martial, who were already at the club before Mourinho.
The BBC Sport pundit claims United executive vice-chairman Ed Woodward has had enough money from the owners to build a successful side.
But former Scotland international Hutchison admits he cannot see United winning the Premier League title anytime soon.

“Why is he not improving Anthony Martial? Why is he not improving Lukaku?
“I think one of the players he has improved, and I’m not sure if it’s Jose or the kid himself, I think Jesse Lingard’s been very, very good for the last 18 months.
“I don’t know if that’s Jose or the kid himself.
“So I think there’s problems there and it’s quite clear to see.
“Tottenham don’t rock up to Old Trafford and beat them 3-0 if there aren’t problems.
“Credit Tottenham because nobody is really speaking about the performance by the Spurs players. I thought they were absolutely brilliant.
“In my opinion, I think Manchester United are way off (from winning the title).”
