I think they should go and play the internationals. In fact I think all clubs should be forced to release players for competitive matches. The Premier League however, should make allowances for teams that lose players as a result.
It's annoying, and I put club above country but for players, representing your country is so important. Its what most dream of, rather than playing a league game. (the chumps league does cloud that a bit more these days)
The conflicting messages aren't good though.
