Adding new players to your soccer team can be difficult even under the best of conditions. The best youth soccer coaching drills can't help egos or prevent cliques from forming. Encourage communication among your team and make use of your senior players. Quite often, asking them for advice or designating a new player to each of them is a good way to make them feel important and respected, they may even take their new players under their wings to show them the ropes (whether they need it or not).
