Former Manchester United boss David Moyes admits he still feels he wasn't given enough time at Old Trafford.
Moyes lasted less than a season at Old Trafford.
He told the Daily Express: “The ultimate high was to be offered the Manchester United job. That doesn't happen unless you have done something well.
“The biggest disappointment was not getting enough time there because I knew we could get through a difficult period. I believe I could have changed the squad around and prospered.
“It still rankles now because I felt I was suited for it. I didn't think it was in Manchester United's DNA to change a manager so quickly.
“But it's another example of how the game has changed over the last 20 years."
