Former Manchester United right-back Paul Parker has admitted Paul Scholes was the best graduate from the "Class of '92".
But the retired England international has also singled out Nicky Butt for praise, highlighting his mental and physical toughness.
The Class of '92 were a group of players who emerged from Untied's academy during the early nineties and achieved significant success later that decade.
As well as Scholes and Butt, the four other graduates were David Beckham, Ryan Giggs, Phil Neville and Gary Neville.
The latter player went on to take Parker's spot at United during the 1994-95 campaign and he was recently asked by the club's website about Gary Neville's emergence.

"The boss would introduce them as 'the players that were going to take your place,'" laughed Parker. "One hundred per cent. That's how it was!"
Before going on to say: "The best player out of all of them was Scholesy. Scholesy stuck out like a sore thumb, without a doubt, with the ability and what he had.
"But Nicky Butt... people started realising what Butty was, and you were scared of him! He was that tough, mentally and physically.
"He wasn't scared of anybody and would stand his ground with anybody."
Scholes, Butt, Beckham, Giggs and the Neville brothers were later nicknamed the Class of '92 because four of them helped United win the FA Youth Cup that year.
Other notable members of the team - arguably the club's greatest at youth level - included Keith Gillespie, Ben Thornley and Mirror Football columnist Robbie Savage.
The Class of '92 were famously written off by Match of the Day pundit Alan Hansen on the opening day of the 1995-96 season when United lost 3-1 to Aston Villa.
Manager Sir Alex Ferguson famously allowed key players Andrei Kanchelskis, Paul Ince and Mark Hughes to leave Old Trafford, putting his faith in the youngsters.
"I think they've got problems," said Hansen at the start of his famous rant. "I wouldn't say they've got major problems.
"Obviously, three players have departed. The trick is always buy when you're strong, so he needs to buy players. You can't win anything with kids.
"You look at that line-up at Manchester United today and Aston Villa, at quarter-past two, when they get the teamsheet, it's just going to give them a lift.
"And it'll happen every time he plays the kids. He's got to buy players, simple as that."
United went on to win a Premier League and FA Cup double that season before lifting the Champions League in 1999.
Scholes, Butt, Beckham, Giggs and the Neville brothers all enjoyed hugely successful careers at club level, with three of them spending the rest of their careers at Old Trafford.
Butt was the second to leave the club after Beckham and is arguably the least talked about of the six, yet those who played with him - such as Parker - hold him in high regard.
The 39-cap England international won six Premier League titles, three FA Cups, four Community Shields, the Champions League and the Intercontinental Cup.
"Nicky cleaned my boots, so Butty was just a lovely lad," added Parker.
"I used to give him boots as well. The boots I used to wear when I came in, he used to always have a pair of them.
"I used to get him initially to wear my ones in for me. Size seven! Butty used to wear them in for me and I'd give him a pair of boots as well, and give him some of my kit."
On the success of the Class of '92, Parker said: "They all supported the team, and they were all in awe of the first team.
"They were all really, really nice kids, and you can see that with what they became, and how they all conducted themselves.
"And when they played, not one of them let this club down. You must say that about all of them."
