Well, KDB playes pretty well for both club and nation, but he is also the main focus on both teams.... However, we never really seen KDB play in a big team or as the second/third/etc option. Mata played for United, but never really came close to the 2012 season he had here in terms of production, etc. I think Hazard probably didn't want to fight for his place as well, but, he eventually turned the other cheek.
