Chelsea manager Andre Villas-Boas has launched a verbal attack on Gary Neville after the former Manchester United defender's comments about the Blues.
The 35-year-old, who now works as a television pundit, had criticised the Stamford Bridge side over recent performances.
One comment levelled at centre-back David Luiz was that the Brazilian played as if he were controlled by a 10-year-old using a PlayStation.
"You can't speculate and invent things that are going on. Some people can have more or less an idea. But not him. He cannot know," said the Portuguese.
"You cannot approach a top Brazil central defender saying he's commanded by a kid with a PlayStation. That's ridiculous.
"What does he know about the Chelsea dressing room? What does Gary Neville know about our dressing room? How can you imagine what is going on in the Chelsea dressing room? How can you know? Have you been here? Do you know where Cobham [Chelsea training ground] is? You don't even know how to get here."
Chelsea host Manchester City in the Premier League on Monday night.
