Ferguson's recruitment was a large reason behind his enormous success as a manager at Old Trafford. The Scot won 13 Premier League titles, two Champions League titles and five FA Cup in a 38-trophy haul.
"There were three categories," Neville said on Sky Sports. "His policy was to promote youth wherever possible, that was number one before he even looked at the external market.
"Number two was to look at the best in the Premier League, those he could trust, and still have growth and be with the club for a long time. Gary Pallister, Steve Bruce, Wayne Rooney, Rio Ferdinand, Robin van Persie.
"And then he always wanted emerging international talent that could come over to Manchester, that he could work with and develop into great players. Nemanja Vidic, Peter Schmeichel, Patrice Evra, Cristiano Ronaldo, Ole Gunnar Solskjaer.
