Manchester United legend Gary Neville is critical of Sir Alex Ferguson over claims he worked with only four world class players during his time in charge.

Ferguson wrote in his new book 'Leading' that he felt only Ryan Giggs, Paul Scholes, Cristiano Ronaldo and Eric Cantona were worthy of the title.

But Neville told Sky Sports: "The one that stood out for me is Peter Schmeichel. He was definitely from my career at Manchester United a world-class goalkeeper.

"If he wasn't a world-class goalkeeper then I don't know what was. Roy Keane, as well."
