Lampard is expected to become the eighth England player to reach 100 caps in tomorrow's crucial World Cup qualifier with Ukraine in Kiev.
It will be another milestone in a magnificent career that has seen the 35-year-old win three Premier League titles, four FA Cups and captain Chelsea to glory in both the Champions League and Europa League.
The doubts expressed so early in his career have all been answered.
But Lampard has never forgotten them, especially one particular afternoon when he accompanied then manager Harry Redknapp to a fans' forum in Romford and found himself the subject of a pointed attack from the relative of a player who had just been released.
"I'll never forget it," said Lampard.
"Everyone has their opinions. He voiced them at a young kid. I thought that was wrong.
"I know exactly who it was but there are no individual gripes.
"He's probably quite tough anyway being from east London.
"But some people do forget it was tough, or they try to change history and say it wasn't like that.
"It was. I had the nepotism one thrown at me regularly there and as a kid I found it quite hard to deal with.
"Certainly that day I did."
Any idea Lampard was getting an easy ride because of his dad was misguided anyway.
Even today, Frank senior is never scared of offering an opinion.
"He won't praise me for the big things I do but he will have a go at me for not tracking a runner or doing the basic dirty work," said Lampard.
"He will ask me if I have been doing my sprints in the week.
"I am 35 for God's sake. I just humour him nowadays.
"Dad put that work ethic in me, though.
"As a youngster, he always made me very aware of my weaknesses. He would go on about my pace, getting in the box, scoring goals.
"He let me know there was no easy way to get there. It was extra runs, extra hours practising shooting and finishing. It became ingrained in me.
"In my younger years he probably bullied me into it a bit.
"I didn't always like it but I can't thank him enough for it now."
