Chelsea boss Thomas Tuchel says he was "not impressed" by Mike Dean admitting he made a mistake in their 2-2 draw against Tottenham Hotspur.
He said he should have told referee Anthony Taylor to check the pitchside monitor.
"A mistake that big and obvious the whole world sees it," Tuchel said.
"I struggle to be fully impressed by the statement. It's so clear and obvious, I cannot understand how a referee cannot make the right decision," he added.
Tuchel and Spurs boss Antonio Conte were both sent off at full-time following an angry confrontation on the touchline and have both since been charged by the FA.
