Sir Alex Ferguson says he only worked with four "world-class players" as boss of Manchester United.
Manager for 26 years, the club won the Champions League twice and 13 Premier League titles during his time in charge.
But he says in all that time only Paul Scholes, Eric Cantona, Cristiano Ronaldo and Ryan Giggs could be described as truly "world class".
So who missed the cut?
Here's our starting 11 of "not world-class players".
Goalkeeper: Peter Schmeichel
Image caption Played nearly 300 games for United and was captain in the 1999 Champions League final. Ferguson struggled to replace him when he left. Massimo Taibi anyone?
Right back: Gary Neville
Image caption Not only David Beckham's best mate but a solid full back with 85 England caps. But still join the back of the queue Gary
Centre-halves: Jaap Stam and Rio Ferdinand
Image caption The scary Dutch defender Jaap Stam also played for Lazio, Milan and Ajax. But not quite "world class" according to his old boss
Image caption Rio Ferdinand was once the most expensive British player in history, Ferguson paid nearly £30m for him to not be quite "world class"
Left-back: Denis Irwin
Image caption Played for United for 12 years, ever present in the successful Ferguson teams of the 1990s. He also played more than 50 times for the Republic of Ireland
Right midfield: David Beckham

Centre midfield: Roy Keane and Bryan Robson
Image caption Ferguson's midfield enforcer and captain played more than 300 games for the club also captained the Republic of Ireland
Image caption England legend Bryan Robson played nearly 100 times for his country as well as winning two Premier League titles and three FA Cups with United. But not as good as Paul Scholes?
Left midfield: Andrei Kanchelskis
Image caption The Ukrainian-born winger was known for his fluid attacking style. One of only 13 non-British or Irish players to play on the opening weekend of the Premier League in 1992
Centre forwards: Ruud van Nistelrooy and Wayne Rooney
Image caption Rooney is England's top goal scorer of all time having scored 50 times while playing for his country. Still, could have played better for Fergie
Image caption A mere 95 goals in 150 matches for United, Ruud van Nistelrooy who also played for PSV Eindhoven and Real Madrid. Ruud not to, Sir Alex?
Image caption Welsh international forward Mark Hughes is a hero at Old Trafford. He also played for Barcelona and Bayern Munich
Image caption Steve Bruce was regarded as the bedrock of United's defence in the 1990s. But he's not in Fergie's top four
Image caption Gary Pallister played for United for nine years and alongside Steve Bruce formed one of the best central defensive partnerships in the club's history. But Gary, you were not "world-class"
Image caption We think Argentina international striker Carlos Tevez deserves a place on the bench in Fergie's B team
Image caption Dwight Yorke and Andy Cole formed one of the most prolific strike partnerships in the history of the Premier League. But they could have been a little bit better, apparently
