Former England manager Glenn Hoddle remains in a "serious condition" but is "responding well" after falling ill at the BT Sport studio, a spokesman said on Sunday.
Hoddle, who began his career with Tottenham Hotspur and also played for Chelsea and Monaco, works as a pundit for the broadcaster and was taken to hospital after receiving medical attention at the studios in east London. BT Sport subsequently cancelled their football results show, which was due to go on air on Saturday.
"Glenn remains in a serious condition in hospital after suffering a heart attack yesterday. He continues to respond well to treatment," a spokesman said on Sunday.
"The family are grateful to everyone in the football family -- and beyond -- that have sent kind messages of support, they are very much appreciated.
"In particular, Glenn and his family would like to publicly thank the BT Sport staff that treated him immediately on set following his collapse. 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."
