A- Each league has its heights and lows. There was a time when the Dutch league was a force to be reckoned. The EPL skipped what I call its golden era (ie the time when Gullit, Van Basten and Rijkaard) burst into scene because most of those talent were hoovered by either Italian or Spanish clubs. However the EPL enjoyed some exceptional talent such as Stam, VDS, Bergkamp, Hasselbaink and of course the goal machine itself RVN. In our prime ie when responsible adults were doing the decision making at the club, the Dutch league was in its heights while the Championship was struggling. That means that we were focusing more on the Dutch league rather then the Championship
B- The Dutch league has the advantage of providing talent on relatively cheap and to be able to give them European football experience. That's something the Championship can't do. Whittaker might be killing it in the CH but his experience against top opposition is limited to say the least. By the time an EPL comes knocking the typical Dutch player would probably have a couple of caps with Holland and had played in the CL/Europa league.
C- Its easier for the likes of Ajax and PSV to attract good foreign talent as opposed to clubs in the Championship
D- We allow the managers to bring his own players in. Since SAF retired 2 out of 5 managers (Moyes, LVG, Mou, Ole and ETH) were Dutch.
The championship had improved in recent years. I hope that we give a close look to the likes of Leif Davis (1 year left in his contract), Kiernan Dewsbury-Hall and Morgan Whittaker
