Huysegems is so slow and labored to turn, run, make decisions. Makes the transition bloody hard work. And his total reliance on his left peg is also irritating. Amazing he played a dozen or so games for Belgium.
Huysegems had good quality players next to him in the Belgian team which allowed him to do reasonably well in that particular setup. He simply was not the top player of the Belgian national team. Ditto Cunningham for Costa Rica.
Consider the aging but classy Alessandro Del Piero - he won quite a few games for Sydney FC singlehandedly last season, but can't win them all (and is of course well into his late thirties). Shinji Ono is younger, fitter, and certainly one of the top Japanese players of the previous 5-7 years. Our (WPX) imports are not their respective national teams top players. So I would not overestimate the qualities people like Huysegems or Cunningham (or Hernandez) brought to the Nix. They are good players but not good enough to turn a match by themselves. In his prime, Hernandez was probably good enough to turn a game around for Melbourne Victory, until he got slow and overweight and went to India. In his prime, Ifill could turn the game around for the Nix, and is an example of a key national team player (like ADP or Ono), it's just that Trinidad and Tobago are not in the class of Costa Rica let alone Belgium, Japan or Italy.
