"The minute that [executive vice-chairman
Ed Woodward] gave Mourinho a contract extension - which some would say was unnecessary part way through a season - but believing in a manager, showing the faith, he had to then buy him the centre-backs," Neville told
Sky Sports News.
"Irrespective of the manager, Manchester United need new centre-backs. My view is that [Harry] Maguire and [Toby] Alderweireld would have been good options. If they cost £120m to bring them in, then that's what you have to do.
My view would be that he's got to stay until the very end of that contract and be backed until the end of that contract if you're going to give a contract extension as the CEO of the club.
"At the moment, there is definitely an angst there between the club and the manager. Don't get me wrong - the club has supported him. But you can't three quarters build a house - you have to finish the job. United need serious football people to guide what they are doing.
