According to 'Marca', English football wants to avoid a brain drain. The Jadon Sancho situation is the best example of the gap between professional football and reserve teams is too wide.
"Developing players in England is a problem. B teams aren't allowed and we have a development vacumm for players between the ages of 17 and 18", explained Manchester City CEO Ferran Soriano in 'LeadersWeekLive'.
The exit of Jadon Sancho perfectly reflects the problem facing English football. "We couldn't find anywhere to develop him adequately and German teams were asking for him. Now they want to sell him back to us for ten times the price that they paid for him. It's bad, something needs to be done".
Those reserve teams are included in the Professional Development League, a level below Premier League 2. In it, B teams from England's biggest clubs face each other with the same system of promotion and relegation and also participate in cup competitions, There is also the Premier League International Cup, where under-23 sides fight it out from all over Europe.
The situation is, obviously, shaped by the fact that the big teams still don't want to send their best players down any lower than the first-team squad. For this reason, many clubs from across the continent come hunting for their hottest talents and find footballers who have already matured and are ready to shine in other competitions.
