since vulture cant provide you with proper stats, ill post some u21 players on top of my head comparing with leao
Dusan Vlahovic 10.067 km | 2712 minutes
Dejan Kulusevski 9.412 km | 1760 minutes
Ivan Ilic 9.177 km | 1561 minutes
Alexis Saelemaekers 8.893 km | 1896 minutes
Sandro Tonali 8.755 km | 1421 minutes
Lucien Agoume 10.472 km | 781 minutes
Tommaso Pobega 8.882 km | 1101 minutes
Nicolo' Rovella 10.566 km | 982 minutes
Rafael Leao 8.754 km | 1875 minutes
I've only posted midfielders and forwards, I've skipped defenders..if they'd be included then just some notable ones
Matthijs De Ligt 10.236 km | 2026 minutes
Matteo Gabbia 10.432 km | 602 minutes
Andrea Carboni 10.467 km | 868 minutes
Sebastian Walukiewicz 10.534 km | 1717 minutes
Gabriele Zappa 9.772 km | 2381 minutes
Marash Kumbulla 8.781 km | 1106 minutes
so Leao is by far one of the worst u21 players in terms of distance covered. he kinda makes it up if you include all the 30+ grandpas
also the fact that he was shitting on palacio before
Rodrigo Palacio 9.462 km | 2252 minutes
