Huddersfield will soon forget paying to watch a second string play if they manage to win the play offs. I personally don't see anything wrong with a manager selecting who ever he wants for whatever game as at the end of the day it's his neck on the line. He has made sure of no injuries and rested his key players for what is a bigger and more important game. If it results in a team getting relegated or closer to relegation then so be it. They obviously deserved to be in that position regardless of other teams managerial decisions.
at the end of the day, each team has a squad of players to choose from so I cannot see an issue. Also, if he gives the younger players a chance, surely that is good as it means we could yet get more English players playing in the divisions thus enhancing our national team should they be any good. And the only way you can identify whether they are any good is to play them
