Brian McDermott believes managers should be able to appeal key decisions during matches to stop accidental refereeing errors.
The Reading manager was asked about contentious handball decisions, including one which led to an opposition goal in their draw against Cardiff on 19 March.
"I think managers should have two calls in a game," the 54-year-old told BBC Radio Berkshire. "You couldn't see replays, but you could make an instant call."
"It's a hell of a difficult one to call though if you're a referee or a linesman, they don't get it wrong deliberately."
