Toa Samoa rugby league coach Matt Parish says NRL clubs are continuing to stand in the way of players who want to play for their country, and something needs to be done.The New South Wales assistant coach says every player he has spoken to wants to play in the upcoming Four Nations but a handful of NRL clubs continue to make things difficult.\The clubs are very selfish at times and they stand in their way. What they don't realise also is these guys playing in the better competitions make them better players. [Anthony] Milford came back from the World Cup last year brimming with confidence because he played really well for Samoa against the worlds best. We are having trouble with clubs releasing them. I don't think it's very right and I'm hoping that the NRL will step in and assist us in that. It's something that I've discussed on numerous occasions
