Arsenal chairman Peter Hill-Wood is recovering in hospital after suffering a heart attack.
The 76-year-old has been battling pneumonia and was taken ill at home on Friday, according to a statement on the club website.
It read: "Peter is making a good recovery. The club wishes him a full and speedy return to health and our thoughts are with him and his family at this time."
A small group of Arsenal supporters called for Hill-Wood to step down from his position on Saturday as part of a protest demanding change at the club.
