Money doesn’t produce talent. Top of the range training facilities, pitches and gyms do not produce talent.
Producing local or even more widely British talent is as much down to pure chance that a club just happens to stumble upon or scout an innately talented kid or group of kids at any one time, as it is anything to do with what any clubs do or how much they invest.
Over the decades, South American teams have had awful training facilities but have produced many of the best players over the decades because their kids have a ball at their feet for hours and hours a day from when they could walk which allows more of the innately talented kids to shine from an early age.
Celtic produced a great football team of local lads that won the European Cup by the pure chance that all those kids came through their Academy at once (it had never happened before and it hasn’t happened since). United produced half a team of their own players by pure chance that they all happened to come through their Academy at the same time (it had never happened before and it hasn’t happened since). Barcelona produced a great football team that Pep first coached who were the core of winning three trebles in a decade by pure chance that all those players came through at the same time from their Academy (it had never happened before and it hasn’t happened since).
There’s nothing particularly good about Celtic, United and Barça’s Academies as history has proven that they were all just one-off occurrences that a group of kids just happened to all come along at once. There’s never been a conveyor belt of talent coming through all the time through the decades at those clubs, and there hasn’t been anywhere else they’ve got a lot of money to put into their academies neither.
Phil Foden, by pure chance, just happened to be born with innate talent. He’s said just recently that he’s had a ball at his feet from when he could walk, he used to have a ball at his feet all the time, he’d dribble the ball to the shops to get milk for his Mother, he’d be out in the street playing football until it got dark… he was already a very talented kid before City even managed to scout him. He just happens to have been born in the local area and happens to be a City fan.
