Former Manchester United boss, Wilf McGuiness discusses whether it will ever be possible for David Moyes to live up to club legend Sir Alex Ferguson.
In 1969 McGuiness took over from Sir Matt Busby, who was the most successful manager in United's history until Sir Alex Ferguson. McGuinness was in charge for 19 months until Busby returned.
He goes on to say that Moyes is capable of being a "terrific" United manager, but advises the Scot to "be himself".
