Andre Villas-Boas has launched a scathing attack on those who criticised his decision to keep Hugo Lloris on the field of play after being knocked unconscious by Romelu Lukaku on Sunday.
FIFA's chief medical officer, Professional Footballers' Association head Gordon Taylor and brain injury charity Headway all hit out at the Tottenham manager for not substituting the goalkeeper following the collision.
Lloris needed lengthy treatment on the pitch and the Tottenham manager said afterwards that the Frenchman could not remember the incident.
Spurs insist Lloris was fit to continue playing following thorough checks by club doctor Shabaaz Mughal and physio Geoff Scott.
It is this criticism of the club's medical staff, who saved Fabrice Muamba's life at White Hart Lane two seasons ago, that has riled Villas-Boas so much.
"I stand absolutely by the decision I took and I stand by the decision that the medical department took following the checks that they made on the player," the Tottenham manager said in a fiery press conference on Wednesday afternoon.
"All the checks were according to the book.
"I have registered the fact that a couple of people have taken this opportunity to find the chance to get themselves publicised who have no experience in the pitch whatever in these type of situations.
"And I find it extremely disappointing that two people - a great doctor and a great physio, who saved the life of Muamba were heavily put into question by lots of incompetent people, with absolutely no experience on the pitch, no experience in the action, no experience in the moment.
"That is extremely serious and disappointing."
When asked if Scott and Mughal were angry about their conduct being questioned, Villas-Boas said: "Yes, of course."
