Great column written by Christian Pulisic. Worth a read and the reason you should always try to train and play with the best.
“In the U.S. system, too often the best player on an under-17 team will be treated like a “star” — not having to work for the ball, being the focus of the offense at all times, etc. — at a time when they should be having to fight tooth and nail for their spot. In Europe, on the other hand, the average level of ability around you is just so much higher. It’s a pool of players where everyone has been “the best player,” and everyone is fighting for a spot — truly week in and week out. Which makes the intensity and humility that you need to bring to the field every day — both from a mental and physical perspective — just unlike anything that you can really experience in U.S. developmental soccer.
Without those experiences, there’s simply no way that I would be at anywhere close to the level that I am today.”
