The Tottenham manager is about to enter his third season in charge at White Hart Lane.
Tottenham manager Mauricio Pochettino
Tottenham Hotspur manager Mauricio Pochettino has revealed in an interview with Fifa.com what he would tell his 20-year-old self if he could, also discussing the moment that he conceded a penalty against England in 2002.
His comments are an insight into a coach famed for his work with young players, and perhaps help explain why some of the younger members of the Spurs side have thrived under his management.
"When I was younger I thought I already knew everything," Pochettino told the Fifa website. "I thought I was already too good for anyone to teach me.

"If I could say one thing to a 20 year old Pochettino it would be listen to your coaches. Listen to the people with experience and you'll become a much better player and person.
"As a coach I'm always thinking a bout how I can get my point across in the correct way."
With such an approach, it's no surprise that the likes of Dele Alli, Harry Kane, Ryan Mason, Eric Dier and Danny Rose have all come on leaps and bounds under the Spurs boss, while at Southampton Luke Shaw, Adam Lallana and Victor Wanyama all flourished.
Before he took over at the Saints, the Argentine was most famous for his challenge on Michael Owen in Japan that led to a penalty in the 2002 World Cup. It saw England banish the disappointing memories from the 1998 World Cup where Argentina knocked the Three Lions out on penalties in the last-16.

But the Spurs manager told the Fifa interview that Liverpool legend Owen had admitted to him in private since that he was never touched in the challenge, even if the ex-England man maintains in public that he was fouled.
"Michael and me both agreed that I didn't touch him at all and it shouldn't have been a penalty," said Pochettino.
"We discuss this in private of course. He knows I didn't touch him but publicly he has to say I did touch him."
With Pochettino having demonstrated a genuine knack for accommodating young players and bringing them into first team football, it is perhaps not a surprise to see that he has solid advice for youngsters and continues to get the most from young sides.
