Back in 2013, Sir Alex Ferguson revealed the one player he would most definitely include in his all-time Manchester United XI.
"People ask you who is your best Man United team. It is absolutely impossible," he said during a Q&A session.
"You look at the strikers I had, going back to [Brian] McClair, [Mark] Hughes, [Andy] Cole, [Eric] Cantona, [Ruud] van Nistelrooy, [Louis] Saha, Ole Gunnar Solskjaer, [Dwight] Yorke, Teddy Sheringham.
"Then to the present players, Wayne Rooney, [Robin] van Persie, Chicharito [Javier Hernandez]. How do you pick out of that? Cantona and somebody else?
"The midfield was probably a bit easier because you have [Roy] Keane, [Bryan] Robson and [Paul] Scholes, they were fantastic players and [David] Beckham, [Cristiano] Ronaldo and [Ryan] Giggs.
Sir Alex went on to say: "But honestly, I would say Denis Irwin would be the one certainty to get in the team. I called him an eight out of ten."
A left-back by trade, Irwin was one of United's most illustrious players from 1990 to 2002. A set-piece specialist, he scored 33 goals in 529 appearances for the club during that time.
