Ashworth's exit has particularly angered Butt, who minced no words to express his disappointment in an interview with the Daily Mail.
"Over the years, Man United has looked like it's a plaster on a gaping wound," he said. "It doesn't work. They haven't got the finances, they have to get their house in order, they have to be a proper football club that work to a design, an ethos and a recruitment drive of how to get players in and get them out for big money. Obviously, they've got rid of Dan Ashworth, which I thought was a strange one, having worked so hard to get him from Newcastle. I think even if you got David Gill and Sir Alex back there, it's going to be a struggle for a long time. We're at the bottom of the mountain and there's a massive climb to get up."
