Bates told Yorkshire Radio: "I see he's rather unwisely been giving an interview in which he says the players are tired, a sense of jadedness among certain players has proved telling.
"Well, I don't quite understand what he means by that because when we play QPR we'll have played 50 games, but everybody at the club will have played at least 48, 46 league games and two cup matches.
"I don't understand what he means by players being `out on their feet' after playing so much this season. It certainly doesn't apply to him. As far as I can see, looking at the fixture list, as far as I know, he has only played twice in the last six games.
"So I don't think fatigue can contribute to his contribution, which I haven't been particularly impressed with."
