Wilder hit out after their 1-1 draw with Burnley.
Wilder said: “Drinks breaks aren't actually a drinks break. What they are is a tactical time out.
“Listen, I didn't think anything should be changed, midway through a season. Whether it be substitutes or whatever, because it's not really a drinks break, is it?
“It's a chance, to be honest, for managers to take a tactical look at their team.
“Listen, we use it as well. I can't pretend that we don't. But I'm not sure, with the temperatures hardly rocketing sky high here at Burnley, that we needed a drinks break. It's just turned the game from a game of two halves into a game of quarters."
