Johan Cruyff has said that it was a "basic mistake" to appoint David Moyes as manager of Manchester United.
Moyes arrived at Old Trafford as Sir Alex Ferguson's successor, but spent an unhappy year with the club as they finished a disappointing seventh last term.
"Manchester paid for their stupidness and now they have got to recover," Cruff told BBC Sport.
"Moyes is a very good coach because I've seen many many years in Everton, but he's not a coach which should fit with Manchester United because the focus for both teams are totally different.
"That's why the biggest mistake is to ask Moyes to come to Manchester United because it's a totally different team, a totally different mentality. The basic mistake was to sign him on. I think he is a great manager, but not for Manchester United. He's just a great manager for another type of team."
Louis van Gaal has taken the reins at Manchester United following Moyes's dismissal, but has only won three of his eight games in charge so far.
