With the COVID-19 pandemic hitting football clubs' finances around the world, Europe's top organizations are looking to their youth teams rather than to transfers for ways to freshen up. Already this season we've seen teenagers like Borussia Dortmund's Giovanni Reyna, Arsenal's Bukayo Saka and Manchester United's Mason Greenwood make their names at their clubs.
Not all young players come through a team's own academy, of course, as Manchester United spent a potential €41 million on signing 18-year-old winger Amad Diallo from Atalanta in January, while Barcelona landed Pedri from Las Palmas for €5m over the summer.
