We did several camps, barca camp a few years back - when my son was younger. Good training drills, but they did accept all level players. Some kids did not have soccer experience.
Coaches are not from Barcelona either - they had one guy there. This year we will be doing the Ajax camp, a friend did the camp before and loved it. You have apply to be accepted, small groups and all coaches are from the Ajax academy. High level training and coaches are very personable. Same group is also doing a Dutch Pro camp, same concept.
