Former England manager and Tottenham midfielder Glenn Hoddle remains in a "serious condition" in hospital after suffering a heart attack on Saturday.
Hoddle, who is "responding well to treatment", collapsed after appearing on BT Sport on his 61st birthday.
Sound supervisor Simon Daniels has been praised for giving Hoddle emergency first aid at the BT Sport studio.
Daniels said he "just did what was necessary to give him a fighting chance".
Responding to tweets from pundits Robbie Savage and Paul Ince - who had appeared alongside Hoddle on Saturday morning - Daniels said: "It was my training as a special constable that paid off."
He added: "So pleased that Glenn is now getting the best care possible in hospital. Thoughts are with his family."
Former England midfielder Ince described Daniels' actions as "miraculous".
A spokesman for Hoddle, in giving an update on the former England manager's condition, also highlighted Daniels, saying: "In particular, Glenn and his family would like to publicly thank the BT Sport staff that treated him immediately on set following his collapse."
BT Sport's Saturday afternoon football results show was cancelled after Hoddle's heart attack.
Hoddle earned 53 England caps and was considered one of the best players of his generation.
His spokesman said: "The family are grateful to everyone in the football family - and beyond - that have sent kind messages of support. They are very much appreciated.
"Glenn is now in the care of the professional NHS medical services, who have also been exemplary in helping him and the family during the last 24 hours.
"Doctors have advised the most important thing for Glenn is time to rest. Therefore, his family have reiterated the request for their privacy to be respected during this period."
As a player, Hoddle won the FA Cup (twice) and Uefa Cup with Tottenham and also had spells with Monaco, Swindon and Chelsea.
He began his managerial career as player-manager at Swindon before taking over at Chelsea, for whom he signed Netherlands great Ruud Gullit.
From there he managed England for two-and-a-half years, taking them to the 1998 World Cup, but his reign ended in controversy when he admitted a "serious error of judgement" after suggesting disabled people were being made to pay for the sins of past lives.
He went on to manage Southampton, Tottenham and Wolves, before embarking on a career as a TV pundit.
Support for legend Hoddle
Since news of Hoddle's collapse on Saturday, there has been an outpouring of support for a player who lit up midfield for Tottenham and England.
Alan Shearer, who was England captain under Hoddle, said: "Wishing my old boss Glenn Hoddle a very, very speedy recovery. Thinking of you."
Former England and Tottenham team-mate Gary Lineker added: "Hugely worrying news. Thoughts are with him and his family. Come on Glenn." Ex-England and Arsenal forward Ian Wright said: "Hang in Gaffer."
Current England captain Harry Kane wrote: "Thoughts are with Glenn. Get well soon." Tottenham tweeted: "Everybody sends their best wishes for a full and speedy recovery."
