And no one knows better than Cooper how much of a challenge stopping Foden will be - having once conquered the world with the new sensation of English football.
That was back in 2017 when Foden inspired Cooper's England U17 side to World Cup glory in India.
Cooper admits he knew back then what a special talent Foden was, someone so in love with the game he would spend hours practicing with a ball at his golden feet in the rooms and corridors of the team hotels.
He said: "It's brilliant to see him doing so well. He is full of confidence now and a fantastic talent. He's a brilliant lad and it's great to see him succeeding at a high level.
"He's a very likeable lad and team player. I remember when we were in India he had the ball at his feet in his room and on the corridors all the time.
"That group was like that anyway, they had a lot of love and understanding for the game and Phil epitomised that. I didn't see the final bill and I turned my phone off. I left that all to the girl in charge of team operations. That was without the darts and cricket that was going on as well.
"You saw a fantastic player every single day. He was a pleasure to work with. But he's always been like that. Just a natural on the training pitch and in games. He's growing up always being himself.
"He's just a nice lad. If you haven't got humility you cannot go on to become a top player. It's as much about having the right character as it is the talent and he's a great example of a player having the right attitude."
Foden, who outlined his stunning potential with a virtuoso goal to help City destroy champions Liverpool 4-1 at Anfield on Sunday, is one of several rising stars from that group who ruled the world under Cooper, to go on and star in the Premier League.
Cooper, who has kept in touch with Foden, reckons he can be the leader of a new 'golden generation' that can go on and do something similar under Three Lions boss Gareth Southgate.
He said: "It was about getting the right individuals into the programme to go through the system and play in the under-21s, the seniors with Gareth Southgate.
"That's what you want at the end of the day, to be competitive here and now but also to have the right players to go through the system and get to the end which, in England terms, is the senior team.
"They have a manager there in Gareth who wants that, he's committed to giving them opportunities so all of the England team have high level players but, in terms of the 2000s, they will always be a talking point because we did win the World Cup.
"It's good to see that we had a good team there and individuals are now shining on the Premier League, Bundesliga and on the big stage now.
"That is what, in the end, international football is. It's about being specialists at tournament football. That's why we completely revamped the game programme, didn't play friendlies anymore, just played tournaments and hopefully long term Gareth and the players will benefit from those experiences."
