That's a flaw in football. So many players leave good teams to go to a few top teams like Bayern, MU, Barcelona. Dortmund has won 2 of the last 3 German titles and will probably be in the Champions League final, but that is not big enough for these players? Kagawa left to go to MU. Van Persie left Arsenal, hardly a small club, to go to MU. I hope Bale doesn't go to Real or MU.
